For the moment the save is unfixable, please be patient and wait for the official bug fixes from Mojang in the next few weeks. In the mean time make sure you create a backup before modding, Open 360 Rev > About > Settings > Tick create backup > Save. All backups will be saved in the same directory that 360revolution.exe is. (for example the desktop) Thread locked and moved to Unresolved Issues.
