Cmd_ServerMessage

Client -> Server = Cmd_ServerMessage (24)

This packet gets sent whenever you leave the character selection and go back to the "server select screen".

In response to this packet, the server sents out packet Cmd_ServerList (23) and then Cmd_ServerMessageAck (25)

Since NeoCity only every has one server available, is this packet to be ignored.
