Just completed Soul Cairn and I've still got Arvak's Skull in my inventory, is this normal?
and yes, I've already got the summon spell.
Have you tried selling it or dropping it, this MAY be another quest items still in inventory bug... but I need more info.
My bug was during the fight with the Arch Curator after he lets out a huge blast I found myself on the edge of a mountain and had to jump my way down, thought it was part of the quest at first and I couldn't use the buttons to bring up a map or weapons, I ended up falling down a waterfall and ended up in the dark passage I think it was called. It was pretty weird luckily loading up a save helped
Which quest is this part of and is it part of Dawnguard/Vampire or a side quest.
3. Inability to shift between first persona and third person view on a high level character.
You sure this isn't a controller issue, seem pretty strange to effect only a high level character.
Gameplay bug - only started when I had the DLC no problems before hand.
When I was with Serena and she says we need to go to the collage of Winterhold I get 2 walls in front of the first gate and then the main door into the collage not sure if it's a Dawnguard bug or just a Skyrim bug but thought I would post it anyway :/
Sorry I don't understand what you mean here?
Very nice Code Man!

This needs to be "Stickied".
I was hoping someone would start this kind of thread. It is the only essential way of organizing the problems, for the Devs and the Players. One can just review the OP in lieu of scouring an entire thread (or Forum) to know if i'ts been reported and/or confirmed.
The gracious DarkRider mantled the "Bug Index" for the Beta and done a fabulous job. Every initial report, was categorized under various headings in the OP, like you have displayed. Things separated into areas pending severity and subcategorized into AI, Gameplay, Visuals, Crashes, Dialog, Quests...etc. Each initial report was ended with a (ref) link to the original post...Again, like you have.

Then, when an initial report was "confirmed" by another post or extensive testing of reloading and duplicating the bug, it was relocated into Post #2. The "Confirmed List" that basically mirrored the OP layout.
Again....Kudos!

Thank you, I will break things down into more categories and stuff as the list gets bigger if needed. Also I do need to find a way to confirm these bugs... may have to do something like that.
