Still an issue A21.2 b30. Hubs is hosting, ran into an issue where he couldn't stop punching so I had to quickly grab my drone up and got booted.
When I got back in had this error. Tried the admin privileges with my 7dtd id and jd clear with no success. Trying admin with steam I'd now. Really wish they'd get their multiplayer in order...
Edit: steam ID didn't work either
