Permanent locked lobbies

[zAlfredoo]

I accidentally used the arrow keys to rename the lobby as I was typing the lobby name in the command prompt and forgot that the terminal takes all of those keyboard presses as input for the name, so the lobby with this name attempted to be created:

this resulted in that error popping up and the lobby being created with who knows what password and I can't seem to close the lobby as the command "close" wasn't working D:
(UPDATE) the lobby did close itself eventually after 30 minutes or so.

thanks for reporting.
i added function to remove unexpected character from lobbyname.

by the way lobby will automatically close after 2 minutes of inactivity.
