I am in the Bell Tower at the Musician's Square. I came back up a ladder and nudged the B button on the way up (may or may not be relevant). Now I cannot interact with anything on the level I am on. The game seems to think I am still on the level below. I can see the ladder interaction if I tilt the camera down (see image) but have no way of getting close enough to it to use it. The game has auto-saved...
