"Bergrit's Claws" is bugged.

I'm not the only one who has ran into this problem. When the last bear died, for me, his corpse disappeared completely and I wasn't able to loot it for the last claw. I don't know if I killed him or one of the nearby enemy NPC's killed him (there was a lot going on), but the fact that the bigger grey bears don't respawn at all has left me stranded in regard to this quest. I ran around circles for a solid hour in the designated quest zone looking for the quest bears to no avail, only the normal run-of-the-mill bears. I'm not going to wander around aimlessly at what I know if a foregone conclusion.

Restarted the system, restarted the save, etc. etc. and nothing as worked.

What's going on?
