I clicked save and exit as usual, next day i went to open the world and it said "load failed no backup found" or something (pretty sure i had a backup though). it wouldnt load but the actual world was still in my worlds list. now a day later i went to check and the world was gone completely? it was a new world i made for 1.4 and spent only about 35 or so hours on it which isnt too bad but still kinda sucks i might have to restart again. Is there a way to get it back?
