FOR NEW PLAYERS:
On the latest 2.2.9 update, if you're having issues trying to start a game, there is a workaround. Just press the Saves on the elevator screen then go back to the main menu and start. Everything should be fixed.
I don't think I'll be able to update since I have a lot of content added now. If anyone says they having an issue starting the game, let them know this workaround and it should be fixed.
