I cant look him, he is the end boss at forgunthur crypt or whatever, part of the lost legends quest line. I kinda need his [censored], but I can't loot him.

nevermind, I just loaded an auto save and killed him first, all is well....for now.

Okay, I have been noticing that I can not loot certain corpses again, so this problem needs to be fixed by a patch...it always seems to be the nord undead, dreag or whatever.
