I found online that it could be someone in the party that is making the enemies bug. I tried to switch out gale and everything works, but I really like him.
Do you think that my save is ruined? I would like to not go back (I'd lose like 4 hours of gameplay)
It sounds like those experiencing this have run into an unresolved script tied to the Auntie Ethel fight since every example I've come across noticed the issue either immediately after that encounter or in the Underdark, where people typically go afterward.
Did you experience any issues with that encounter? It could easily be tied to the Dialog at the end not properly activating or completing.
