I created a map/scenario in world builder. It worked fine and I played it for a bit, then stopped to correct some errors I noticed, specifically three rivers that weren't fully continuous and moving a start location by a hex. When I attempt to start a new game with the updated change, the game hangs on the loading screen. I hear all the narration, and even waiting several minutes after it stops, the game still does not load. I can load all other saved games and custom maps just fine. I don't have any antivirus software. I have tried restarting. I also have tried resaving the worldbuilder file under a new name. Why can't I start my journey?
