One for the Missing/Limited Features:

There's no way to tell if an NPC is marked as Essential (can't die) unlike Oblivion with its "crown" icon. This wouldn't be a problem if the Essential flag was properly being removed from NPCs who don't require it, but this doesn't always happen, most notably in the main quest where the commanders of the faction the player is fighting against remain immortal.

Keep in mind some Forsworn are called Looters and Pillagers.

I see them as angry pagan bandits, myself.

Azzer, this is only one of the symptoms of a far deeper problem. I can't seem to find it's description in the OP.
It is related to the bug with particles, which causes the following to not being displayed: clouds on the 3d map, some of the spell effects (particularly fire), dragons' breath, waterfalls etc. It also may cause black dots/patters on the screen.

I suffered from it too from day 1 and the solution for me is ENBSeries patch - I'm using v4 (0.091) without any optimizations and it fixes it. I'm currently on 115th hour and everything is good.

List up to date. I also included a recent bad experience of my own ...

When trying to deliver the thirty Crimson Nirnroots to Avrusa, all sorts of fun proceeded to unfold. A pair of Orc Hunters (like regular hunters, except they're as territorial as bandits) chased an Elk right into Sarethi farm. The first sign of this was Avrusa suddenly breaking her dialogue. I didn't know why -- there were no sounds of dragons or other battle yet -- so I simply re-engaged her in dialogue, which worked fine. First I told her about Sinderion's death. This is when I heard the sounds of battle. I assumed the guard was taking care of wolves or a bear. The dialogue with Avrusa did not break even as the fight was going on, but I exited after the Sinderion exchange to find out what was happening.

Avrusa's sister was already dead. Avrusa unleashed a lightning bolt (!!), smoking the Orc Hunter. She then ran over to her sister's body, looked down at it, made a pained sound, then ran into her house, inconsolable. I still had not turned in the Crimson Nirnroot quest (callous bastard that I am, I was thinking 'reward' and spared no thought for the poor woman's sister). Picking the lock on the farmhouse, obviously, produced a 5 gold bounty for me, and it was pointless anyway -- I was trespassing, so I could not engage Avrusa in dialogue. I emerged and paid off the bounty to the farm's guard.

Then I noticed the second Orc Hunter standing at the edge of the farm. This guy has the nerve to thump his shield and tell me to back off. The guard does nothing, despite watching this Orc's buddy murder one of the farm's owners. I approach the Hunter to try to engage in dialogue, and he goes hostile. The guard joins the fight, attacking the Hunter, reasonably enough. I make the mistake of defending myself and somehow get an assault and a murder bounty put on my head for killing the Hunter. This would have involved me getting dragged off to Riften, where I had no intention of ending up. Between this and the apparent loss of the Crimson Nirnroot quest, I just loaded an earlier save (and ended up losing quite a bit of progress).

Moral of the story -- all sorts of unsavory characters can wander into a civilized outdoor area (only small ones I'm guessing; towns are probably shielded), and the inhabitants of those areas cannot always be expected to act rationally.

Interface/Engine:
'The game won't let me use any special characters of "my language" when naming a character but can display them just fine, haven't checked naming enchanted items cause the lack of an enchanter char.
German characters to check:


There seem to be problems with other languages as well like spanish etc. I saw at least one other lass/dude having this bug.
It was posted in a post patch 1.2.12.0 thread user said it didn't happen for him before 1.2.
Since I rolled back to 1.1 I can at least say for me this problem existed before 1.2 was rolled out.

i found thazt game (1.1) can't detect savegames after a time

http://www.gamesas.com/index.php?/topic/1301707-sava-geme-dissapearing/ the thread. anyone can confrim?

Alik'r hoods wont fit well on Elves and Kahjiit. Elves ears sticks out through it and almost half the kahjiit head.
Also with the shrouded hood.

What Kosh Vadar mentioned - I've noticed that too. I am sent to wipe out bandit lairs/Forsaken/etc. (by the Jarls) - but if I hit them with ranged in sneak to get the crit bonus it logs it in my stats as an assault.

Here's a bug that I'm not sure has been noted... because it's overly specific. After 1.2 loaded while I wasn't looking, random encounters... broke a bit.

I was at the bandit cave with the blind lookout. Low level, so I was scrounging everything to sell for my first house. Fought a random bandit chief outside. Went inside, cleared it out. Went out the front door and saw the traveling bard guy fighting bandits. The corpse of the chief was missing. Went to town, sold stuff, came back. The corpses of the other bandits from the encounter were missing, bard was missing. The encounter with the corpse with the note about how bandits stole her family heirloom was in its place.

The encounter spot just seemed to be randomly cycling encounters while cleaning up all sign of previous encounters.

Saling goods to my spouse-follower Mjoll Lioness doesn't give me money. Saling goods to other vendors works OK. Is that just another bug of last patches? Can anybody else confirm that?

You linked to a wrong video with Viarmo glitch.
There are actually two glitches there. The http://www.youtube.com/watch?v=Yd-6Y9TdMDY instead of liting the effigy, and the http://www.youtube.com/watch?v=tsNllbHapDI after the festival.
Didn't make a video for the second one at first.

Also, I've gone through "Arniel's Endeavor" again. Here are his phrases: http://cloud.steampowered.com/ugc/596955603750192513/C6885721874DB3EC7A326E5D516250AEA4DB08E8/, http://cloud.steampowered.com/ugc/596955603750190501/34E42704BB3B191A966C348A7CFF81A9A86A16D0/, http://cloud.steampowered.com/ugc/596955603750187333/3CC3965D6B86536724D23146D0E817035813DBFB/, http://cloud.steampowered.com/ugc/596955603750195288/3F92C5DC7B9E9823DD50A8BA7D4A4BD9F1C79307/, http://cloud.steampowered.com/ugc/596955603750193933/67E2C2D0859E9F087D0309941557A65141089DDA/. Don't think there's any more info on Keening in Skyrim.
He doesn't mention Wraithguard - yet he is surprised PC's not dead. That may mean that he may have found some way to resist that damage. Which is improbable considering Morrowind info, but whatever. I guess, we don't have enough info to consider one side or another, so just let it be on the list.

Nearly the same issue for me. I got attacked by roadside bandits that were living under a cliff. When I checked their locked chest all the bodies disappeared after closing it. Also this bald dude from Rifton keeps showing up all over the place and getting killed by an orc hired by Maven.

You can add this to radiant:
-The Greybeard quests possibly are the cause of a bug which prevents the shout word from appearing inside the Hag's End dungeon. If this bug occurs there is no way to gain that shout word.

Two bugs I have a hard time overlooking (spoiler alert!):

1) INVISIBLE DRAGONS - I mean, really? At first I thought the bush was casting ice breath on me, but then I realized the dragon was invisible (also only had about 1/4 health).
[img]http://www.freeimagehosting.net/45af4[/img] <-------------Notice the floating arrow?

2) MOROKEI NOT RENDERING - 50% of the time the Morokei mask (the mask you receive after killing the boss for Staff of Magnus quest) doesn't load/render, and neither does my characters head (note: I am also wearing the Arch Mage's robes, which has an attached hood).

So... http://cloud.steampowered.com/ugc/596955603754999688/3CDD37073EDA4519EFE592577642077346B7E3CE/ and http://cloud.steampowered.com/ugc/596955603755003063/550DADC9E98E1226AE1C9E08A1E0A00A6D4FA85A/ happened today. The strange thing is, this a) did not happen to all the NPCs in the Bee and Bard, and b ) when I first walked in they all had their faces... and hands... God this one is creepy.

So, this seems to be happening all over my game since the patch. Hair is keeps flashing in and out of existence as well as people's skin.

I am trying to play the game as a stage 4 vampire. However, after any city is liberated by the stormcloaks and then has stormcloak guards (every city for me), they do not recognize me as an enemy and therefore do not attack me.

The townsfolk however do see me as an enemy and proceed to attack. Once that happens, the stormcloak guards attack anyone who is red to me (everyone) and kill them.

Hm, more than one bug thread... only just saw this one. Don't know if these have already been mentioned.

Don't know where to find the game version I'm running, I have the Steam version and viewing update history from the game properties (in Steam) tells me absolutely nothing! It's just a news page.

• Can't "Kill the dragon located at Bonestrewn Crest" given as a bounty by Jorleif of Windhelm. Best description is here: http://answers.yahoo...29200508AAeYCoE
  

  I went to mountain top. No dragon. Found and activated "Cold" Shout. Saw dragon indicated on map. Moved to that location, see link.At one point I returned to try again. There was a second dragon, that attacked and was killed. The quest remains open.

• Cannot active top shelf of book case nor can I read any books on top shelf
  
• Cannot drop/store/sell "Strange Amulet" for completed quest "Blood on the ice".
  

  At one point someone (Jorleif?) mentioned talking to Calixto about the amulet but after talking to Hjerim I returned to Jorleif and the quest was completed. Now when I talk to Calixto he has no dialog option for the amulet.

I just visited the Thalmor Embassy for the second time AFTER completing the quest which takes place there. When I came the first time and picked the gate open I wasn't attacked on sight but after killing one of the guards.
Now on my second visit I can kill guards in-front of their comrades without being attacked and to make it funny I picked up one beheaded guard in front of a living one holding the corpse up.
He said something along the line of "Whoever did this will pay for it"

Didn't see this in the list of bugs, but maybe I missed it:

- on multiple occasions, while swimming deep underwater in lakes and ponds, I saw wildlife running across the bottom of the lake/pond as though they were not underwater. No extra resistances, nothing, just running around 30 feet under water. Foxes and rabbits specifically.

This happened pre 1.2. Haven't seen it since but probably just that I haven't spent much time in water the past few days.

Haha sorry couldn't help but laugh - that's actually kind of humorous. I'm sure it's annoying in-game.

I haven't married in game yet, so I'm not sure how shopkeeper spouses works yet. Normally, you don't barter with followers. You can give them items or take them away freely, and if they have gold in their inventory you can take that freely too. From what I read, if they open a shop, you get 100 gold pieces out of the profits every now and then.

Can anyone else confirm this? Do spouses who become shopkeepers generally barter normally?

The major problem I have with that update is that my character seems to be walking or running on slipery ice or mud and he's contantly trying to keep his balance...

In regards to * Louis Letrush NPC can become duplicated - three copies of him have been seen, all standing close to eachother.

Not sure what details were listed previously, but my experience was after giving him the stolen horse he road off and we both headed to Whiterun. When I arrived, http://i216.photobucket.com/albums/cc105/zinnikeys/Skyrim%20Bugs/ScreenShot377.jpg, in the spot you show up in after fast traveling, and it looks to me like he might still be saddled on the horse.
After quite some play time doing all kinds of stuff I had no further issues, though he was still stuck in the same spot. Even left and returned to Whiterun on a couple occassions during that time. But earlier today I loaded a previous save where I'm by the Khajiit merchants and immediately a duplicate comes running over to stand next to him. This didn't happen in the uninterrupted game play. But if I load that save he comes running over every time.

Need clarification on this. Do you mean when Arngeir points you toward a word location?

I've been running round with a frost ghast (is that their name?) stuck under my character. Nothing I have tried gets rid of it. I walk round everywhere with smoke trailing me. however cool it looks, it is now annoying me.
