Corrupted save file?!?!!

[cherrychomp]

Hello! So, I have a problem on version 15 of the game. Earlier today, I downloaded some earlier versions of the game: Versions 1, 11, and 13. Problem is, I just went back to version 15, but my save file isn't loading, and it's my only one. I have EVERYTHING on there, and I didn't back it up. Is there ANYTHING I can do? I really miss my characters

Right, This is the same thing that happened to me! I havent been active on the game for 4 days and it corrupted and disappeared, I was very sad to see all my progress go to waste i even tried everything.. But it didnt work! It might be happening for everyone. Plus, This happened TWICE for me.
