"World corrupted" when trying to load anything
Me and my friend are playing ME together (I'm being the host) in a world maybe a week old. Since yesterday (2019-02-22) my friend cannot join my world: when he tries he get to 18% loading and then gets a message that the world is corrupted and cannot be loaded. We tried older backups thinking the world got corrupted but same issue occured. After that trying to load any world on his side (even any of the default new worlds without any mods) resulted in said message. On my side everything seems to work fine.
He has tried to check his files with steam, even a full reinstall of ME. Nothing seems to help.
I'm attaching our save, logs of both of us and printscreen of that error message.
