Since halloween my server won't load sav files for the world. Every restart fails to load the previous file with the console message 'Error loading save' and then creates a corrupted world with a duplicate name with a number on the end eg. (1)

When using the command 'server.save' in game, it just creates a new duplicate sav file.

Can anyone please help?

Paste the whole error message
