So I loaded up minecraft and went to my main map only to see its screenshot picture the generic black and white and the size wrong. It was nearly 600 mb and now shows 29mb and when i try to load it minecraft completely crashes back goes to to the main xbox dashboard and if i go to the maps settings it does the same thing. I've restarted the xbox, uninstalled and reinstalled minecraft and cleared recent data to previous point and nothing works but I have other maps that are unaffected
