When in a multiplayer game and you have the train window open and get into jumps you can not close the train menu to reach the main menu to pause or quit the game. Effectively locking your game in this state until the jumps stop.
Steps that occurred to cause this bad state:
- Be in a multiplayer game
- Open a train orders GUI window of a train
- Enter the Jumps state, when you are behind the server in UPS and the multiplayer statistics says you have jumps.
- Press escape to try and close the train orders GUI and then again to try and open the main menu
- The train orders GUI will close and before the main menu can be opened the train orders GUI will flash back. You are now stuck unable to reach the game's menu.
