I really don't like that someone can go and chop a tree/chip a boulder and all the quests go poof. At the least it shouldn't count as a failure for purposes of credos, where it counts as abandoning the quest, potentially losing a lot of progress. It's not really our fault, and there's not much we could do short of claiming every questgiver in the area (seems a bit over the top).
This probably was suggested and answered before, but why can't we have questgivers transferring to a random object in the near area on death?
