I was recently working in my Attack of the B team world when suddenly the game crashed at first I thought it was no big deal but upon relogging the game crashed with the last thing poping up being downloading terrain. I went into the world file only to find the level.dat file was just gone like it deleted itself. I tried multiple things like deleting all the data relating to temples and villages and stuff. To importing the level.dat_old file into MCedit, to my surprise all the blocks were there however when I tried to export a selected area as schematic MCedit pops up an error. I can't think of any other things to try and fix this problem. I was hoping someone on here may have some solutions and ideas on how I might be able to fix this problem. Below I've also attached the crash log.
