My most recent world got deleted when i reopened my game

I have been working on a private world and just finished my Nether castle that i put in a lot of hours. Today i started my game and before i could access a world to join, my xbox overheated due to the warm weather right now. My xbox turned itself of to prevent overheating and when i got back into the game my most recent world (the one in question) was gone. Only this world and not any else. Is there a way to get this save back?
