[Solved] Corrupted .mca file

Deleted the world and had no further issues.

Apologies in advance if this is in anyway incomplete.

So I don't entirely know how I would go about explaining my issue. The issue is when removing a mod which adds any block( e.g A modded ore), then going through /fml confirm process the server tries to make a back up of the world. That is where the issue starts; Forge fails to make a world backup (that is also sometimes a fully corrupted .zip file) then forces an immediate stop of the sever(essentially crashing).

Well here is everything I have to help.

Side note: AromaBackup has the same issue creating auto saves(doesn't crash just fails).
