Or we can't forget the "waking nightmare" quest were erandur disappears once he enters the temple....yeah its very frustrating because now these is no way to become thane of dawnstar.

How about Aela never gives Totem missions... just endless Extermination quests.

Bumping this up in the chain a little. Hoping this becomes a resource for devs to correct issues.

-Kill the Hagraven Petra: I killed the [censored] before letting Malka out of her cage and now the marker just points to the dead body of Petra.
-Locate Valds hunting party (given in Falkreath): Went to where marker was and found a hunters camp, two female hunters there but no Vald. They won't talk or interact. Now i can't select/deselect the quest from the journal.
-Collect bounty from Skald: I talked to Skald but never got the bounty and the quest never finished.

For Forbidden Legend, there is another bug if you clear Geirmund's Hall before being told to go get the amulet fragment.
Since the boss is the one supposed to drop it and he doesn't respawn, it us impossible to get the amulet fragment by re-clearing the dungeon.
All you get is te arrow pointing at the location where you killed te biss the first time but not corpse or object to pick up.

Riften quest 'Supply and Demand'. Cannot complete the quest for the Jarl which results in being unable to become Thane and purchase the home in that city etc.
Cleared 'Cragslane Cavern' before going to Riften and getting the quests. After getting the quest I returned to the cave and 3 bandits were present (1 outside, 2 in - fairly sure it was only 2 inside but possibly 3. One was where the bandit leader resides, however). After disposing of them the quest did not complete.
Wiki reports waiting some time might respawn one or more of them and upon killing them again it may complete. This has not been the case for me thus far.

Very disappointed.

The Old Assasin/Hag's End - Cannot get the word, I have learned the first shout time word, found the second in Kvorlunder or whatever and learned it but it did not show to learn... cant use word 2 now at Hag's End will not get word Eternity.... All music and chants no word.
Misc Quest: Waiting on Brelyna's first spell still to wear off.
I am level 44 and over 400hrs in the game...

I've got two glitched Daedric quests, the dead Lod problem and the infinite loop Boethia conduit.

Finishing either one is the only thing needed for my platinum trophy.

I'll try to avoid spoilers about this even though it is very minor part of the Dark Brotherhood questline.

Dark Brotherhood quest "Bound Until Death";
After entering Solitude and heading towards the target area to complete the contract/quest the game starts to show signs of preparing to freeze. Anytime I approach the area to do the job it always ended with a freeze. Sometimes before and sometimes after doing the deed. I cannot get out of Solitude before the game freezes. It caused the PS3 to have to check the HDD each time and erased all auto-saves after the fourth time.
It took me about 7 tries before I was able to succeed. I avoided going through any doors after entering Solitude and it worked on the first attempt. I loaded a full save from before going to Solitude on this attempt. Each of my freezes I used doors to move about the area where the quest occurs to get into position. I don't know if this is relevant, but thought it was worth sharing.

Also, bump! This thread is important.

During the Civil War storyline when siding with the Stormcloaks, I constantly get no one to show up at the Fort attacking missions (Sunguard, Snowhawk and Hraggstad). Since no one is there, I cannot kill the imperials and cannot complete the quest.

Exact same problem. And I note this bug is reported in several places when doing a general web search. And I further note that this is only one of many reported bugs I have encountered.

My real question is whether anyone at Bethesda is LISTENING! Sorry for coming across a bit frustrated and upset, but I know the transaction of giving my money for this game went through without any bugs! Is there SOMEONE/ANYONE at Bethesda that is able to respond to these bug reports with even a HINT as to timeline for some (I would not presume ALL) of the fixes to these bugs in your product?

Happens at the Eastmarch Imperial Camp too, during the "Regain Eastmarch" objective.
Also, as mentioned on the post above, a lot of times the Forts are empty, or soldiers disappear before 100% clearing them.

I have this problem also. It appears to be related to marrying her or using her as a follower.

I was very happy to see this post. I have a few more:

The Argonian Dereethus bugs out after you marry him and try to send him back to your house. He runs home to manage the store everyday back in Darkwater Crossing. I have had to just keep him there because otherwise he sometimes never comes back at all.

Moon Sugar Rush - Thieves Guild quest does not appear after the second quest from Tonilia. I have heard she gives it to you after you finish all the city influence quests sometimes.

After clearing out the spiders in Redbelly Mine, they respawn and kill all villagers the next time you enter the mine.

The little quest to help Telvar at Nilheim never triggers his "guards" and you never get your "reward."

Sometimes I won't absorb dragon souls from dead dragons. Even if I reload and refight several times.

Sometimes the Bedlam jobs from the Thieves Guild will only count if you steal from the keep of the targeted city.

I cannot upgrade my Nightengale armor even with the right skills and perks.

I also have some quest items stuck in my inventory (not those heads, but the strange amulet, Bard instruments, unusual gems which are not stacked, but displayed individually, etc), but they actually do not take up space for me (although they are given weight in the descriptions).
You can verify this by storing everything you can into a container and look at your current carried weight.
It is annoying though that I now have quite some items in my miscellaneous list which just sit there.

"Skald" is the Jarl from Dawnstar. He has nothing to do with the Companions quests. You've got this glitch under Companions quests.
Also, quest items that get stuck in your inventory do NOT count towards your total weight. Test it for yourself. Empty everything else in your inventory and your weight will be 0.

I see some other discrepencies in your list as well. You should double check and comfirm things before adding them to this list. Isn't going to help much if you're giving Bethesda incorrect information.

Don't forget about the Louis Letrush glitch!! That's a pretty popular one that's all over the internet.

I will not be updating the original post with quest bugs anymore. Please feel free to take the list into your own posting and revise it to make a more accurate list.

I have a couple of miscellaneous objectives that simply won't clear.

1. Helping the people of Solitude (5/5). This remains in my questlog even though I've already done this, AND gotten the reward.
2. Investigate the Bard's college. This is apparently (according to the uesp wiki) a known bug that happens if you start the "questline" (by joining the bard's college) beforing completing this miscellaneous objective.

Just got a misc. objective from the Riften steward. "Kill the dragon at Northwind Summit". Problem is, there's no dragon there. Seems like this type of problem can happen in many places.

same happened to me i even redid the quest it's still not there ,its frustrating

I am so unbelieveably frustrated at these quest bugs. I'm not usually one to complain about bugs, but I really want to enjoy this game.

the latest one? The Leader at Redoran's retreat, who I killed for an earlier quest, is now represented by an arrow sitting where his body was after I killed him. I cannot complete the Companions "attacking the heart" quest, I cannot finish the companions, and I cannot lose werewolf status. Ii know I'm one of a million complaining about these, but please test and fix these glitches. This is a potentially great game, but as a long time supporter of Bethesda games, I am very, very disappointed.
