That player name is already connected

[Shadow Wizard]

I am getting this error when a player tried to reconnect after an unexpected disconnection. How do I fix this?

IN the event I havent explained things connected:
Player "John" connects to the server. All is well. Player plays a bit with us. Player "John"'s computer crashes. Player "John" tried to reconnect. Player "John" received a message "That player name is already connected"

Other then waiting for the player to time out on the server, or restarting to server, how do I fix this?

Under Connections you can boot a player.
