Issue happens infrequently, but enough to notice and be annoying; probably two out of five times.

After hitting "Save and Quit", the game hangs at "Generating world", "Loading Resources" going back to the main menu, and never recovers. Have waited 5 minutes+ at this screen. The only way to exit is to go back to the Xbox home and force close the app. If you do this, the next time the game is launched, it gives a message that it could not load the global resources and has to reset them.
