Bump to the front, can we someone message a mod to maybe sticky this for easy reference?

Quest: Buying a House in Markarth/Becoming Thane in Markarth

Type: Side Quest

Description: Upon completion of the Jarl's quest to retrieve his shield, he offers to make you Thane if you buy a house and help the people. He directs you to speak with the steward about buying the house, but the steward gives only canned dialogue, and no option to inquire about the house.
How To Replicate: Inquire about the house in Markarth at any time before the option to buy is given, or inquire about the house without having the necessary funds.

Stats: Level 27

*Quest: Killing Ennodius Papius
*Type: Dark Brotherhood
*Description: Questmarker doesn't disappear from Ennodius Papius after killing him and the Questlog doesn't update!

Other: Started the Dark Brotherhood Quests after completing all other Questlines ! Error occurs with and without the newest patch ! Its not possible to continue the story with this bug:(

*Quest: Glory of the Dead
*Type: Companions
*Description: When I am supposed to attend Kodlak's funeral, no one does a thing and the funeral does not start.
How To Replicate: Some people have said that someone of the companions is "stuck" so that nothing happens.
Stats: Around 40lvl and ~70h
Other:This -of course- stops my companions quest line. There have been other people with the same problem and there is a "bugfix"-video on youtube but it didn't help me. Also, I had a problem with giving a letter for the Jarl of Whiterun but I "fixed" it with the help of the "bugfix" for Glory of the Dead. After getting the Jarl to talk to me, he walks away from the skyforge. No idea if that has anything to do with the bug.

Link to the video: http://www.youtube.com/watch?v=cMQrwhybGAA
Another bugfix, this time through console (I don't know if it really works): http://www.youtube.com/watch?v=DyRroQ-I1to

Quest: A Cornered Rat
Type: Main Quest
Description: After completing "Diplomatic Immunity" Delphine does not give me the next quest "A Cornered Rat".
How To Replicate: Being a member of (not personally confirmed) or the leader of (personally confirmed) the Thieves Guild.
Stats: In the 30's when this happened.
Other: Delphine's dialogue changes if you are a member of the Thieve's Guild when she is describing your next quest. This may have something to do with it.


Please! I can't continue playing because of this Please please please!

QUEST: THE CURE FOR MADNESS

TYPE: Dark Brotherhood

DESCRIPTION: Behold Shadowmere. Or not. I just completed BREACHING SECURITY. I waited in whiterun till the victim got there in the pub and killed him in his sleep while my companion waited at the original dark brotherhood sanctuary. Go to report to Gabriella and get quest cure for madness. Talk to blond lady, search ciceros room and take all his journals in order 1,2,3 ect. Talk to Astrid again and exit sanctuary. Follow arrow to tar pit. I hear Shadowmere stoping and snorting, tar bubbling. Wait, wait, wait for it. Nothing. Walk into arrow in tar pit nothing happens, no evil hourse for me.

HOW TO REPLICATE: unknown. First time I tried I had left my companion at the sanctuary while I did all the other darkbrotherhood quests. Also I took the books out of order and skipped (tapping A every time Astrid spoke) dialogs.
I noticed when I came out to find Shadowmere Aranea (azura follower) had left on her own back to the azura shrine.
Second time I tried I reloaded to before I had completed BREACHING SECURITY and sent follower away. Completed that quest getting Bonus in pub same as before, talked to Astrid, listening to all dialog, got books in order, talk to Astrid, listening to all dialog, no Shadowmere, same bubbles and sounds.
Third attempt. Load back 2 quests to solitude save,BOUND UNTIL DEATH, shoot the lady without being detected, Argonian attacks me when he sees me (not brotherhood one, ja ree or something), guards don't care about me. Go to sanctuary tell follower to go home, get bono u's and next quest BREACHING SECURITY, fast travel to Katlas farm, buy a horse to change 2 c factors, ride to dragon reach. Haikus talks to hai father who is invisible this time. Fast Travel to Riften. Kill giaus in town. Go to sanctuary get bonus the hourse I bought is outside I pick up only quest boomafter talking to Astrid. Astrid as always says "look we have to deal with this situation" then camera goes to her and she says it again finishing the sentience. And no Shadowmere yet again. So disappointed.
STATS: level 53, 70 hours, 309 saves thru 3 characters 2 of which were deleted when I started over.

OTHER: svcks to not have a sweet evil horse. Let's get on the ball developers!

*Quest: Blood On The Ice
*Type: Side Quest
*Description: Can not find Viola to progress the quest. She appears to be stuck underneath Candlehearth. I can see the quest arrow that is supposed to be over her head in the ground when I walk around Candlehearth.
How To Replicate: Unknown
Stats: Redguard, Level 29
Other: Someone mentioned on Skyrim's Wiki that when they used a noclip code that they found her dead body under the ground under Candlehearth. This can be read at: http://www.uesp.net/wiki/Skyrim_talk:Blood_on_the_Ice#Viola_in_unreachable_place.3F

Quest: Scoundrel's Folly
Type: Thieves Guild
Description: I'm at the part of the quest when I'm told to 'Confront Gulum-Ei'. But the objective marker is pointing off the map in a north-westerly direction when I'm in the East Empire Company Warehouse and I can't actually find the arrow on the local map. It doesn't even tell me to progress to the next area which is a cave system, once I do it just tells me to leave out the back of the cave and once there, the objective marker tells me to go back into the East Empire Company Warehouse.
How To Replicate: When the quest tells you to 'Shadow Gulum-Ei' I just followed him while sneaking until he entered the warehouse. Once he did I waited a moment then picked the lock and once I was inside, the objective arrow was pointing where it is now, except I didn't imagine it was glitched and just went and got the East Empire Shipping Map from the cabin on top of the hill while picking off all the enemies.
Stats: I can only base this off estimates from my previous saves as it happened a while ago now and I was hoping it would get fixed. I had been playing for around 30 hours and I was around level 30.

*Quest: Jarl of Falkreath: Becoming Thane

*Type: Radiant and or Misc Quest

*Description: The Jarl of Falkreath will not offer me his fetch quest, or his subsequent bandit quest, only his two dialogue choices show up

How To Replicate:No idea, try speaking to him before the main quest and without helping anyone

Stats: LvL 50 Main quest not completed, DB, Companions, Civil War completed, MQ, TG and MG not completed and started partly, some other radiant quests are active

Other: The steward has given and I have completed her quests including killing random bandits and giants. I have also invested in every shop and done most if not all other quests available in the town including Daedric quests. Any help is greatly appreciated.

Quest: The Forsworn Conspiracy
Type: Side Quest
Platform: XBOX 360

Description: After searching Weylin's place and exiting the Warrens, I am accosted by a guard who takes issue with my snooping. He decides we need to have a brawl and there's no way to avoid this fight. Once it's initiated, every guard in the near vicinity becomes hostile and all attack me at once. While I did not have weapons equipped, I did have a set of Glove of the Pugilist on, but this bug seemed to persist even when I reloaded the game and didn't equip them. Also, it must be noted that the guards are immediately hostile after initiation of the brawl - not a single blow has been thrown when the red dots appear on the compass.

Stats: I have been playing for 100+ hours, and was about 3/4 of the way to Level 51 when I attempted this quest. It had languished on my quest log for quite some time, as well. I deliberately have no followers (you guys need to fix them so they don't try to constantly stand in the spot I'm already occupying, but that's a separate issue). I have completed the Civil War questline, so the Stormcloaks hold the city, but I have no idea if this has any bearing on why this happens. At the time I attempted this quest, the only questline I had left was the main one and I'd done that one up to, but hadn't started, the "A Cornered Rat" quest.

Quest: Alduin's Wall

Type: Main Quest

Description: While in Sky Haven temple, I activate the blood seal, and a door is revealed. As I walk towards it though, Delphine and Esbern run away. They run away to the spot in the temple where you have to turn these three pillars. They stand still, and I can't get them to move without attacking them. I can't progress unless they come through the door with me. I'm playing on the xbox but I found a video of a PS3 user that has the same problem as me. Hopefully it helps:

http://www.youtube.com/watch?v=qYa4acPrNMA&lc=a61dtDp794XH1CgqevvIDzhBe4J-_mQqEz3fohCuuho&feature=inbox

How To Replicate: I am not sure how this has happened. This may be the problem. Earlier in the game, I had come across Sky Haven Temple and completed all the puzzles. It wasn't until later that I had to go there for the main story. I simply fast traveled to the temple and spawned right in front of the blood seal. I went right ahead and activated it. I didn't have to do any of the puzzles with Esbern and Delphine since they had already been completed. I didn't even have to fight any of the Forsworn since I just fast traveled right into the temple. This is the only possible cause that I can think of.

Stats: I was a level 24 when the problem occured.

Other: I know that I am not the only one with this problem as some of them have told me that they were having the same problem.

Have you tried waiting? I did that and I had to wait many hours for the spell to wear off.

Quest: Forsworn Conspiracy
Type: Side
Description: I completed the quest and at the end I fought a little bit to help the forsworn uprising. Now I am wanted by the guards in Markarth and can not pay my debt. my options when the guards talk to me are : bribe, go to jail, or i'd rather die. if I try to bribe it doesnt work, my speech is 48. I try to go to jail and it just starts back with him telling me I am wanted. This is stopping me from doing anything in Markarth.
How to Replicate: I guess kill some guards when the forsworn rebel.

Quest: Disrupt the skooma operation
Type: yarl quest in riften
Description: I got to the end where I had to kill the boss and right out side the cave a dragon was trying to kill me. I did not feel like fighting it so I went into the cave, either once I got into the cave or once the dragon tried to kill me, the quest glitched and I can not complete it. I am not sure, but the quest is there and I can mark it, but I can not view it on the map and it says no quest is activated.
How to recreate: do the quest and run from a battle into the cave maybe.
Other info: I have cleared this cave before for a previous quest I think. Maybe this changed things, because when I went into the cave I only had to fight one guy in the beginning of the cave and the boss. the dogs/bartender and others were not there.

I have. I could try waiting some more. But I doubt that'll work.

Dont have the thing in front of me so this is to the best of my memory

*Quest: Mages college Arniels Gem
*Type:
*Description: Essentially you have to put the warped gem into the dwermer convectors and heat them. However after the first one worked, subsequent attempts in other convectors dont work.
How To Replicate: Just pick the quest up. I picked it up after i was the head of the mages, not sure if this matters.
Stats: lvl 42, about 130 hours of play,
Other:

Anengerr, have you gone to the Ratway? I don't remember him actually going there when i completed the quest, though he was there when i showed up at the Ragged Flagon. Might want to try it out, idk.

Its saddening that this thread is so long

I'm not refuting the glitch you've experienced, but this was not the case for me, as I had a stone of Berenziah before starting any thieves guild quest. It seems quite a few people are experiencing this particular issue with the thieves guild.

Quest: Retrieve Arondil's Journals
Type: Misc (received from Thieves guild member Vekel the Man)
Description: When you return to Vekel the Man to turn in the books, the quest completes but he does not take the journals from you or give you the gold that he has apparently awarded you. Luckily the journals can be discarded after completion of the quest and do not clutter up inventory.

Quest: Find 5 Ice Wraith Teeth for Marise (0/5)
Type: Misc
Description: After handing in the quest to Marise - the food vendor in Riften - the quest stays active but reverts back to 0/5 and collecting ice wraith teeth does not effect the quest anymore.


Quest: Talk to Brynjolf about joining the Thieves Guild
Type: Theives Guild / Misc
Description: Listed in the Misc section but linked with the quest to join the theives guild. Once completed, stays in the mission log.


Quest: Return to the Jarl of Riften
Type: Misc
Description: After asking about becoming a Thane of Riften, you are told you need to buy a house in Riften. Once the house is owned there is no dialogue to continue, so the mission is stuck as active and you are unable to become a Thane in Riften.


Quest: Find the copy of N'Gasta! Kvata! Kvakis!
Type: Misc
Description: Obtained the book before meeting the quest giver, and as a result, I am directed to Northwind Summit to retreive it, but can't. And also cannot drop it from the inventory as it's marked as a quest item.
Other: The quest giver is Urag gro-Shub in the Mage's College library.

*Quest: Bound Until Death
*Type: Dark Brotherhood

Other: Will bug out on giving reward, you lose the bonus even though you met requirements.
