I just went through the ruined villa last night. What would have been really entertaining turned out to be the only frustrating case of necessitated constant save-loading I've experienced in the game.
I used two characters, a rogue and mage, unchained to navigate through the rooms. When I stopped one on the edge of dangerous terrain, like poison, and switched to the other, the first character who should now be idle apparently thinks he's standing in dangerous terrain so he moves out of the way immediately--invariably moving THROUGH said dangerous terrain and causing poisoning and usually explosions. The same thing happened in the poison 'garden' prior to the villa. There seems to be fuzziness around AI automatically relocating from dangerous terrain so that if they're even close to it (not necessarily in it) they'll relocate, and when they relocate they don't mind truly endangering themselves. This is making navigating heavily trapped areas which should be a lot of fun anything but.
I'd like the ability to truly stop characters who aren't chained to the currently active character.
