I installed a nevernude model that was more Nord-looking in my opinion and also some clothes to use with bodyslide and one of the dresses was clipping so it would cover the entire screen in an eternally shifting void and crash if I looked directly at it. 10/10 would play again.
I actually had no idea what was causing it until it happened in a different area of the game and then I connected the dots that two NPCs wearing exactly the same item of clothing affected by mods were in those locations. Otherwise I’d have never fixed it and just been effectively banned from 2 taverns.
