//Puzzle Spoilers
Found a [DATA MISSING] room. Here are the steps:
1. Go through the motions in the original house on a fresh save.
2. Do the chair pentagram puzzle thingy.
3. Go into the hallway with the bird sounds (behind invisible wall).
4. Fall off the edge WITHOUT interacting with the question mark at the end of the bird hallway (I'm not entirely sure you don't have to press the question mark, but it worked for me).
5. Once the game closes open it back up and you will be in the living room without any furniture. At this point, wait around until some morse code plays and the music stops. (btw the morse code translates to "Learn The Way Of The Old Wind").
6.After the music stops go upstairs and interact with the door and go back down, there should now be a clock in the middle of the living room. Walk around it and interact with the green door at the back of the room. You will now be at a screen that says [DATA MISSING]. Idk what to do past this. You have to delete your save to return.
