I'm getting the crash sometimes but only when Gale uses Gaseous Form, Either when getting in to it or out from it. Not every time but arount 60% of the times. I never get the crashes elsewhere. Also, it seems that if I use that spel again at the exact same position (from a save and not moved from the spot) it crashes over and over, but if I just move Gale a couple of meters it works, so it seems it has to do with the environment graphics.

I'm using Vulcan, havent tried DX11.
