After the piano room when I wake up in the bathroom, all the doors are locked and I have nowhere to go. :( The door where Robin and Mrs. Hannover left says Interact but nothing happends.
This bug was found recently. Unfortunately, I cannot easily fix it. The way around this is to restart and go in the door Robin and Hannover leave in and then go through the piano room after the library scene.
I apologize that this has caused you some headache!
