Consistent crashing in Forgotten Vale.

I've had very little crashing throughout this playthrough, the only two previous crashes are a consistent crash when trying to enter the Dwemer ruin for Peryites quest and a crash in one of the Dwemer ruins leading into Blackreach (uninstalling Legends of Aetherium fixed that one, didn't fix Peryites though). I just ignored the Peryite quest crash because I could take it or leave it without Spellbreaker, but this is preventing me from actually finishing Dawnguard.
