Just made an account to state that the bug is still occurring. Recently got the game and experienced the same thing - used Medusa Mask with Amiri on a Villain (Mogmurian, specifically), then Amiri moved to another location at end of turn (and used Move-Other as well, in case that's relevant for replicating the bug), and then from the NEW location that Amiri moved to, the Villian was on top of the deck, whilst it had disappeared from the original location. Very unsettling, since I'd moved her in preparation of temporarily closing that location to finish the scenario, and explored once more for a last-chance at loot; not to find the villain having teleported!
