I cannot close the game
I was playing regularly then pressed the manage worlds option. I'm now stuck in an infinite loading screen and anything I do to close the game or shut it down has not worked. Any suggestions are helpful thank you.
acsian If you're somehow still stuck (or just for next time), click ctrl-alt-delete, choose the Task Manager, and kill the game. If you can't see the Task Manager, click ctrl-alt-delete and Sign Out, which will boot you to the Windows sign-in screen and close all running user-mode programs.
Let me know if your game runs into further trouble.
