I was editing around and changing some events. For example, on the map screen a cutscene would trigger that a mansion would explode and the game would make an object appear to make it seem like the mansion completely disappeared. Now, I don't know if it has anything to do with this glitch, but for some reason the character will not walk on a walkable area near the mansion so you get stuck at the mansion. I've tried walking through it from other parts of the map but they can't pass it either. What's wrong?
The problem is caused by one of the changes you made between when it was working before and when it's not working now.
More constructively: Objects block walking by default. Check the BlockingHeight/Width.
