Funny thing is that continuity is kinda respected. Companions keep their new gear when you meet them during act 1 but somehow I stole all their items in the prologue and they spawned with multiple items in their inventory regardless, including new revive scrolls. How did Shadowheart did that? Did she wake up, found some scrolls and then took a nap on the beach? :P

I see what Larian wanted to do there, they aren't really part of the party at this point. Problem is that the implementation is very hacky.
