Yep, that's a Gale thing then. Before patch 5, Origin Gale's dock scene would end after the narrator mentions the Crown and he was directly whisked away to meet Mystra. Now they kindly allow him to at least save Karlach, but the dock scene is still cut short for him and the portion in which Astarion finds out that he was wrong about the effect of the tadpole simply doesn't play.
