I ran into this issue a while ago but I don't remember exactly when it started, whenever I try to speak to Bao-Dur he will just stand in place, turn around to face the exile and keep doing whatever animation he was doing, he will also not follow the party, he's the only one with this problem, if I take control of Bao-Dur and speak to the Exile then the conversation will start normally but it's annoying to have to switch characters if I want to speak to him.
