If a flip occurs while one form is falling into the pitfall, you can end up like this where only the ghost form can move (and it can't leave the room so you're stuck).
Without Birthright this scenario doesn't typically softlock, but something strange does happen when flipping back to the form that fell into the pitfall. He can move but not shoot or interact, and he won't have a walking animation. Only leaving the room will resolve the issue (which makes it usually ok, you do take control of forms after clearing a room usually after all).
