so, in short, I'm doing the dawnguard questline and finally got to the soul cairn. things have been AMAZING so far, great fps, no stuttering, mods work great, only get the occasional crash when I screw up load order, besides that, never. but then I get close to arvak's skull, and ctd. assume it was just a random one, go back in, head back to it, and ctd again. this time I get mad, and decide to just do the main quest I'm there for, and go to talk to valerica. I save there, and go to kill the 3 things, and at the first one, ctd again. reload and just try bringing one to me with it's ref id, and that causes ctd too. this makes me think it's only got to do with anything quest related in there (excluding valerica for some reason, but maybe it's just a coincidence. I have no clue what to look for to change, and googling it hasn't proven fruitful, though someone else did have it (found a thread on steam forums), it seemed like it was never resolved, and was made for skyrim, and not skyrim se. if anyone can help that'd be awesome, because I want to finish the questline and all (and someone else may have the problem) thanks.
