Ok, following a simple server upgrade, I seem to have lost all my progress in your mod, is there any tricks to set it back, I'm OP on my server but have no idea how I would set it back to where I was or which file I need to restore from a backup to get my stats back, any help would be appreciated.

Be sure to update the level.dat > Player folder as well if you're playing single-player.

Nope, on server, wouldn't work, I think I'm just gonna give up on the benefits of this mod if there's no easy fix possible, its a nice idea, but if the data keeps getting corrupted after updates of server and we can't get it back to where it was, its not worth it.

It looks like they changed the NBT in the player.dat file so they either need to push a fix for converting old tags or you need to edit every entry yourself to add the number at the end...

Ouch, I hope for a fix, now I know what went wrong, I'll keep a copy of the old player.dat ready if a fix is possible

This should be a one time process as the NBT was updated to add the meta tag for the food. Unless the developer changes the format again it should stick.

Issue seems to be solved.
