So, I’ve just built the house and everything in it, and I built all the trophies I wanted. That’s when the glitches began.
Most of the trophies all appeared on the same stand and got meshed together. The remaining three were on a different one.
Once all the trophies had appeared, I went into the cellar, and when I came back up, all of my doors to the wings were like this. (See picture) I have no previous saves to reload.
The wiki pages say nothing about this.
