Actually no, it's happening again. In the room with 2 black-yellow dressed, one downed priest and cook in closet, the three are walking around in circles, ignoring my orders to hide. I can tell them to open door and leave though.
But this game is unplayable because it's too hard and requires to sit through the minutes-long beginning if you need to restart. The only solution would be a savestate system it would seem. Hope that's gonna happen, the atmosphere seems really cool.
