I just killed this guy but right before I dealt the final strike he backed into a ante-chamber off of the room where his sarcophagus is. He was searchable but he had no mask. Is that normal? Shoud I load last save and make sure I kill him in his chamber? I read that he is leveled,could be either a Draugr or a Dragon Priest(depending on your level)and if you kill him outside of his chamber he could sometimes be unsearchable.
I honestly have had no real problems since 1.5 came out but had two game breakers before 1.5 And am maybe too over cautious I REALLY do not want to screw myself around on this. Advice/Help please.
Also in my case he was a Dragon Priest and I am level 55.

Curalmil has no mask. He may be a Draugr or a Dragon Priest.
The Masks are as follows - Otar, Nahkriin, Volsung, Krosis, Morokei, Hevnoraak, Rahgot, Vokun, Wooden mask (which you need to gain access to Bromjunaar Sanctuary) Konahrik (foud in Bromjunaar Sanctuary)
