hopefully this board is active enough to help me. I'v placed all of the scraps and then I found the wall, and unless I read the faqs wrong, it said to take off the wall and put the door there, but i cant retake the door from the spot where the portrait was. Hopefully it's not bugged.
Everything has one spot, your game is fine. Door goes over the Portrait. I haven't replayed the game in awhile to know each and every spot by heart, but I remember that the one Wall was tough to place.
Everytime I find the key to success, somebody changes the locks.
