Normally I'd try to figure this out myself, but I've been trying to fix this for several hours now, and there's not an end in sight. Loading new cells seems to sometimes cause crashes, as does everything related to vampirism, but it also freezes on seemingly random times, when walking around, opening my inventory, browsing my journal and more. Well, if anyone is kind enough to look over my papyrus log and tell me what's causing these crashes, that would be great. This one is a bit long, but it has most of the errors that normally show up. http://pastebin.com/J5XHhCpU
