We all know the AI can't drive, but it might pay to keep an eye on things in the dungeon if you use autoplay to get through them. The setup in question was the one with 2 portals and the pigs in a black forcefield box. Usually, the pigs can't be killed until a bird with SS goes through the portal. I've let AI do this setup many times before without problems, so I was quite shocked to find a pig asking me for 50 gems to continue. I hope this was a one off and there's nothing more to it.
