Asynchronous world save potentially corrupting world data

This call is made asynchronously which will call World#save() on all currently loaded worlds - if this is called asynchronously it has the potential to either crash the server or corrupt regionfile data

I see the other call to save in your code is scheduled onto the main thread - perhaps this was left as a mistake?

I would also recommend looking disabling chunk saving when the server is making a backup - the last thing you want to backup is a mixed regionfile. See World#setAutoSave / World#isAutoSave
