Disconnected users cannot reconnect occasionally.

I've had a couple of users mention this so thought I'd open an issue. The latest one said that their wifi disconnected, which dropped their BBS connection. When he tried to relog in the BBS said he was already connected. It seems the BBS didn't timeout his connection for quite a while.

This is probably going to be one of those random hard to pin down issues, but I thought I'd at least log it.
