I don't have a dedicated server, I'm host. I tried looking up how to do it and found this and 2,3 other threads that said the same things.
I got on alone, typing this command
DeleteUserSession(ThePlayer) ThePlayer:Remove()
it disconnected me like it's suppose to, but when I reconnect it just goes back to when I disconnected instead of character selection. Most of the threads I've seen are for dedicated servers.
Thanks guys
