I stopped playing entirely after

the fight with Gortash Enver and Duke Ravengard

because I was trying to take a certain character alive, used non-lethal damage to ensure that this happened, and the game marked them as dead anyway. But because they didn't actually die, it's also softlocked a companion quest.

It's such a betrayal of trust by the devs that I don't know how I could possibly continue the game after that.
