I have this problem too and I’ve been going insane looking for answers. Best I can figure it *feels* like this bug is the same one (as others are saying):
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=902423#Post902423Larian apparently said last week they’re working on it, and people are hopeful Patch 4 might release and address this later this week.
As an aside, it’s sad that Larian not only has a completely game-breaking bug with this many reports since late Sep, but also can’t dedicate one person to spend some minutes answering posts like yours. Our entire playthroughs are broken. You’d think they would act more worried about that.
