This has happened to me twice, both times with Astarion. He was not in my party at the time. No idea what triggered it. Thought maybe I had done something wrong and had a very bad reputation with him. This also happened to someone on the Baldur's Gate 3 subreddit: https://www.reddit.com/r/BaldursGat...attacked_my_party_as_soon_as_we_entered/
