So I started an MC server with some friends. It worked perfectly last night, but this morning I get the error that my PlayerData is invalid. I tried deleting my player data along with my cobblemon player pokemon storage data (for the cobblemon mod). I am still having the issue. https://pastes.io/log-38182 is my latest log, though I am not great at deciphering it. Any help would be appreciated. I have already tried using Packet Fixer aswell. I really would prefer to not have to delete the world.
