Gale needs to stop asking for my loot :V Freaking parasite ahahahha
Seriously! Non-lethal damage is my new way to deal with him now. The second I meet him, BONK, and take all his clothes and items. He needs to start repaying me for all the stuff he ate.
It would really hurt less if Gale had some sort of special ability that other wizards don't have.
Not that I want to talk you out of your dislike, I feel the same way about Astarion, but I do think, that Gale actually might get some powerful ability later on. Otherwise I really don't know, what good his storyline is.
About OP: It sounds like a bug to me. Maybe reload?
