Once you undertake the Thieves guild storyline you will encounter a Thieves guild member (the fence) whom you can initiate dialog with regarding these gems. I'd classify this as not broken.

Quest: Find the copy of The Wild Elves

Type: Miscellaneous

Description: You need to go to Pine Moon cave to find this book, but if you've already been there for another quest to clear out the Vampires (I believe it's a Bounty for Solitude) and have taken the book from the chest, you cannot remove it from your inventory as it's a "Quest Item," but Urag gro-Shub the librarian will not accept it. Going back to Pine Moon Cave and looting the chest again doesn't provide you with another book, and the quest marker stays on that chest. So you cannot hand the book in to Urag and therefore cannot complete the quest.

bump

Probable quest broken: Deliver the Stallion's potion to Raerek.

Description: You get the potion to deliver from Markath's alchemist, but if Raerek has been replaced by the end of the Stormcloak' questline and you haven't delivered it yet (or you got the quest after that), Raerek is nowhere to be found, and the quest marker marks some point inside Solitude's Blue Palace. Needless to say you get stuck with the potion, which is a quest item.

Any idea how to workaround this on PC?

*Quest: The Black Star
*Type: Daedric
*Description: I went to talk to Nevelar and after I talked to him, the icon still shows on him. However, The I on also shows for the dungeon that the star is in. I noticed that the quest log doesn't check off the "talk to Nevelar" part. I go to the dungeon and on top where of the waterfall thing, there a boulder impeding my progress. Nothing I do will get the boulder to move. I have tried quite a bit and I don't have an earlier save. Went in to talk to Nevelar several times and he says the same stuff about the star and the dude who screwed with it.
How To Replicate: not sure how to replicate it.
Stats: Around level 9-10. Logged around 20 hours.
Other: I can't get the Azura Star because of this.

Le Bump

*Quest: First Lessons
*Type: College of Winterhold
*Description: The tour guide will just go about her daily activities and not start any actual dialog with you if she's interrupted during her tour. This makes this section of the quest unable to be completed.
How To Replicate: Either have a dragon attack, assassination attempt, or other random event happen during the tour.
Stats: level 38, mostly thief skills
Other: Read on a different site that if you go to Tolfdir, the quest will automatically continue when you approach him. Will verify when I get home.

Though please fix the game breaking main questline bugs already mentioned earlier. I have the season unending bug, and will likely run into the thieves guild one after I complete that. I'm really disappointed that this patch didn't fix them...

Why I have the feeling Kivan (one of the Unofficial Patches creator) will have tooons of bugs to fix...

*Quest: Seasons Unending
*Type: Main Quest
*Description: So I had started the stormcloaks quest, mainly the very first one where I have to prove myself to Ulfric. Well, didn't think it was going to cause an issue until I went to talk to Ulfric about going to High Hrothgar for the peace talks. First he tells me I have a task to finish for G man, I go to complete the quest and the second step of the quest to talk to G man and he tells me the Peace Talks are pretty much rubbish. I go from G man to Ulfric and he tells me to talk to G Man to follow up on a quest. So the same thing goes on back and forth. So yeah, sorta... stuck, can't complete the quest.

Quest: Dampened Spirits

Type: Thieves Guild

Description: I wasn't paying attention and actually burned 4 of the bee hives instead of only 3. I originally completed the mission, and turned it in. But Brynjolf was unhappy with me (and I couldn't have that), but I had a save right before I started burning the bee hives. So I reloaded it (without finishing the conversation with Brynjolf), and only burned 3. Went back to turn in again, Loud and Clear flagged as completed, but the next mission will not flag. This is extremely annoying, as now I can't complete the Thieves Guild quest line, which is one of my favorite.

EDIT: I forgot to mention in original post, I actually also tried reloading a save back to before even starting the mission, and completely did it all again. Still no change.

How to Replicate: I believe by my reloading the prior save, after already talking to Brynjolf and turning in the quest is what "broke" it.

Stats: Roughly 152 hours of play time at this point.
Level: 52
No problems with loading times

(Still LOVING the death out of this game though!)

Quest: Revealing the unseen
Type: College of Winterhold main quest
Description: When being sendt to Mzulft to search for the staff of magnus there is a dead mage there that you are supposed to loot a key from to gain entrance. (NPCs name is Gavros Plinius) The problem however is that the NPC isnt dead, and talks with generic chat. So you have no way of obtaining the key. Pickpocketing doesnt work either. And I know its a bug since Ive done it on another char!
How to replicate: Dont know
Stats: 18 mage, 11 hours played

Quest. Onmund Request
Type. College of winterhold secondary quest
Description. I save Selveni Nethri (dunmer necromancer stuck in a spider web) from the spiders and told her to leave, but she's unable to do so. She don't move at all or just can't exit the meridion grotto.
How to replicate. No idea
Stats. 35+ hrs played, lvl 28

Quest: Disrupt the skooma operation
Type: Misc Quest for Riften
Description: Final stage in mini questline to stop the Riften Skooma dealers. Quest gave me a cave to clear which I already cleared because of a kill banditleader at X radiant quest. There are two dealer however after killing them. Quest remains active without finishing it and without a marker.
How to replicate: Problem seems to be related towards the same problem people have with certain random Companion Quests.. IE sending you to a cave/dungeon which already has been cleared and either hasn't completely reset yet (to few in game days have passed) or NPC was somehow already assigned to a certain quest before triggering it.
Stats: Level 25

Quest: Take Up Arms

Type: Companions

Description:
After speaking with Kodlak Whitemane, and proving your battle skills against Vilkas they will ask you to run some errands. First you take Vilkas’s sword for sharpening to Eorlund Gray-Mane and give it back to you to give to Vilkas. He will then give you Aela’s shield to give to her. On the map she is displayed as being at Bleakwind Basin with some Mammoths and giants at a burning farm. When you go there she is not there, and the map will sometimes display her being in Jorrvaskr in the living quarters. She is not there either. I have heard she may also be at pelagia farms but shes not there either.

How to Replicate:
Talk to Kodlak Whitemane to begin the quest, and after proving your battle skills and sharpening Vilkas’s sword and getting Aela’s shield try to locate her. Im not sure what the problem could be, my brother has a save file on the same xbox and same game disc as well, and has been able to complete the whole Companion’s questline with no problems whatsoever. Im guessing that he might have ran into Aela fighting Giants at Pelagia’s farm or Bleakwind Basin first before going into Whiterun and going into Jorrvaskr to join the companions. It might be a bug where if you start the quest or join the companion’s quest without having ran into her that it could be Aela isn’t spawned or is stuck in a sort of limbo in the game. These are just wild guesses by the way.

Stats:
I’m not sure when I first started it but it was probably when I was around level 10 or so. Im currently level 26 and still look for her from time to time but no luck. I’ve looked in Jorrvaskr, Pelagia farms and bleakwind basin.

Other:
I would like this to be fixed and I don’t see any way I could fix it, I’ve heard loading an old save file or waiting but neither will work .

Quest: A taste of Death.
Type: Daedric

Description:
After clearing Reachcliff cave with Eola, she asks me to fetch the priest Velrus, so they can kill him and feast on his flesh. Right after I leave the conversation, Eola becomes an enemy, with the red enemy marker, yet doesn't attack me. When I return with Velarus, to the room of the feast, As I approach the doorway, I hear the familiar "what was that" and the people in the room, start to attack Velarus and myself, so leaving me unable to complete the quest. I was level 38 I think, when I first tried to clear the cave, I've since reloaded an earlier save and left it alone.

How to replicate:
I've no idea.


I am also having the return instruments issue with the lute, flute and drum, of the Bard college side quests, though I think this is because I found them whilst completing bounty quests to kill bandit leaders. Though with the drum, I had to go and fetch it, after speaking to Giraud Gemane.

I've also noticed the teleport at the end of Sanguine's Daedric quest, doesn't close and you can re-enter but you have no way of exiting the level.

Quest. A chance arrangement
Type. Thieves guild introduction quest
Description. After i complete this quest, "Taking care of business" doesn't start, and Brynjolf keep making some "mmmfff" noise when i try to speak to him. Quest dialog doesn't start when i go to the ragged flagon, in fact quest doesn't start at all as i am considered here as a perfect stranger.
How to replicate. I think there's a conflict between the thieves guild main quest and the Barenziah gems quest (a strange gem in first instance, to show to Vex). When i pick up a gem before i go to the thieves guild, the guild main quest is broken. Since i wait before picking it up and so starting the gem quest later, thieves guild quest is not broken anymore.
Stats. 40+ hrs played, lvl 30

*Quest: Speak to verulus about the hall of the dead
*Type: Misc
*Description: I have finished this particular quest however this objective is still on my quest list. I did speak to him for the quest but was never acknowledged marker is still there
How To Replicate:
Stats: level 24
Other:

*Quest: Find a copy of arcana
*Type: Mages radiant
*Description: this particular copy is to be found at hags end, my second time there fought respawned foresworn outside went to the chest where the marker is, emptied it but no copy of arcana restored did a reload and also didnt kill anyone just ran over and checked still not there on either accounts. i do have a copy of arcana in my inventory already but i wasnt found or meatnt to be found at hags end but another location
How To Replicate: cant pick up the book before being asked to find that particular copy in that particular location
Stats: level 42
Other:

*Quest: ormunds request
*Type: Mages radiant
*Description: was told to find the staff for enthir so i could get the amulet, i had already done another quest earlier to the lair and found the staff but now it wont give me the option to give him the staff i also have found another one on my travels and i cant get either out of my inventory to put it on a weapon rack in my house which was a suggested fix
How To Replicate: Finding the staff before quest was given
Stats: level 12
Other:

Quest: The Break of Dawn
*Type: Deadric Quest
*Description: I approached meridia's statue and interacted with it to receive the quest. However, when I want to activate the quest to find the beacon, the show on map option is greyed out. Therefore, there is no possibility of finding the beacon and completing this quest.
How To Replicate: I imagine the only way to replicate is to approach the statue. I had just defeated a dragon when this glitch occurred so maybe that is related?
Stats: I had been playing for about 15-20 hours and was level 12-15 I imagine. Hard to know for sure since I'm at 120 hours now and level 58.
Other: Really hoping for a fix here because this quest is part of getting the achievement and I REALLY don't want to roll another character JUST to get an achievement

QUEST :- Hired Muscle

TYPE :- Companions (Radiant Quest)

DESCRIPTION :- Intimidate Erik the Slayer in Rorikstead (yup im sure you guessed where this is going already)

(deep breath) I decided to leave the companions quest for a little later (lvl 21) and it decided my fate would be to intimidate Erik the Slayer, unfortunately i had already been to Rorikstead and met up with the young Slayer Erik and decided (from the history of this NPC) to have him as my follower through dungeon and siege! Alas as i ventured into a somewhat hardened dungeon/cave (whatever) and not one to be put off by a challenge tore my way through each area unwittingly and so far i was doing pretty well for a low level char! (14 @ the time) needless to say Erik was slain in battle (yes i caught him with a spell) and now when i try to initiate the quest stated above it directs me to his cold dead body in the dungeon and i cannot complete this quest! Tried killing Farkas (but we know that doesnt work) tried visiting Erik's body twice with no avail and now i cannot progress any further with the Companions due to this!

Maybe the ability to drop quests would be good in certain situations? Or A way to add resurrection ability on console via character interaction and resurrection phial? (just an idea!)

*Quest: The Cursed Tribe


*Type: Side Quest/Daedric Quest


*Description: You must go to the Orc camp of Largashbur, near Riften. Upon arrival, a giant should be attacking the front gate where a pair of Orcs are defending the camp. One of the Orcs, Ugor, is the trigger for the quest so must stay alive at all costs. However, no matter how many times I reload or whichever direction I approach the camp from, Ugor and the other Orc are already dead when I get there. I've never gone near the camp before and it's marked as 'Undiscovered' on my map. I can kill the giant and go inside the camp but I'll not get anyone to talk to me other than to tell me to leave. The NPC who's supposed to give me the quest, a female Orc named Atub, won't speak to me. Apparently, herself and the late Ugor are supposed to have a conversation in order to trigger the quest but this can't happen now.


How To Replicate: Approach Largashbur. There doesn't seem to be any way to be pre-warned of this location being the starting point for the Daedric Lord Malacth's quest.


Stats: I'm playing the game on XBox 360 (Elite). I'm Level 50 and a hundred and something hours of game time.


Other: I've seen a few complaints about the pre-dead Ugor elsewhere on the web but most of those complaining don't seem to realise that Ugor is a quest trigger.

Quest: Alduin's Bane & Transcribing the Lexicon

Type: Main Story Line

Platform: Xbox 360

Issue: After taking the elder scroll when finishing Transcribing the lexicon, the screen prompt says it has been added to the inventory. When checking the inventory (it should be in the book section) it does not show up preventing me from reading it at the throat of the world and learning the shout to battle the dragon Alduin. The MAIN story can't progress without this step, it's a game breaker and needs a fix asap.

Time invested in the game: 60+ hours

Frustration level: Controler breaking

*Quest: Hard Answers
*Type: Thieves Guild
*Description: Enthir says "This is going to be terrible for business" instead of whatever he's meant to say to allow the quest to continue. He acts like a random NPC, rather than having dialogue options.

Stats: Level 30ish, with at least 65 hours gameplay.

I also have the Waking Nightmare bug, where Erandur has buggered off to the end, leaving me stuck with no way past the statue in the opening room.

http://www.gamesas.com/index.php?/topic/1261724-glitched-quests-you-have-found-list-here/

Putting this here cause you can never have enough bug reports

not so much a broken quest as...just odd.

*Quest: Kill the Bandit Leader (for Annekke Crag-Jumper)
*Type: Misc. Objective / Follower recruitment
*Description: Received "Kill the Bandit Leader" from Annekke and was directed to Gallows Rock, which I'd previously cleared for the Companions quest line. Dungeon completely respawned with all the Silver Hand members, including the "Skinner", that I'd previously slaughtered.
How To Replicate: This seems to be a Radiant quest, so I'm not sure what triggers dungeon selection. I did have Aela the Huntress as my follower; might be a factor.
Stats: lvl 34, dunmer, Harbinger of the Companions

[quote name='ghetto' timestamp='1321987337' post='19407782']
*Quest: Trinity Restored

*Type: Thieves Guild

*Description: On the Thieves Guild mission 'Trinity Restored' I have to "meet Karliah at the standing stone" however when I get to the stone she is not there and nothing happens. Brynjoif is not at the stone either but is infact still in the Ragged Flagon and has no dialogue options. The quest marking is on the stone so its definitely where I have to go. Due to this bug I can not continue which the Thieves Guild questline.

How To Replicate:

Stats: Level 40 , 100 Hours.

Same here was loving the game and the thieves guild too
