[censored]! Good thing you mentioned that. There's really no way to tell if the player has killed somebody, so I had to make the script check whether you are in the same cell as a dead vampire or not. Didn't think of the Bloodcrusties, though. I suppose it's fair that a vampire would get a lot of flak from his kin for not intervening in a situation like this, but it's always annoying to have a quest broken because of a mod. So in the next hotfix I'll make an exception for Bloodcrust cavern in the script.

Speakingly fluently Englishly! You're right that it's awkward. I'll try to make that sentence look a bit more anglo-saxon in the next hotfix.
