I just finished talking to the Dark Elf leader and come outside the house and he doesn't seem to be anywhere! This is problematic because I cannot talk to Raven either, the quest doesn't update. Is there a way to solve this? Is the hi-res patch possibly causing this?

Did you apply the Unofficial Patch? I know that fixes a lot of bugs.

Eh, I was able to just kill her and then Gideon appeared and we were good to go.
