Eh, if im not wrong most of the damage is gone after some time, though i think the burnt down house still remains. Anyway, BLAST HEIMSKR, he's annoying.
You know, it took me FOREVER to notice his little campsite that shows up after his house is trashed. Then my character used it to take a nap. (it was the middle of the day, he wasn't using it.) It's kind of sad that no one will put him up in their house, though.
I have mixed feelings about Heimskr. He drives me absolutely bonkers when I'm in the area, but I don't want anything to happen to him.
