Get stuck in lobby screen, unable to join game

[ghost]

Usually happens after a new player first logs in, or an old player who logs in after a long period away from the game.

You get stick in the lobby. You spawn to an black screen, unable to do anything, but talk in chat. Relogging doesn't work. Clearing the BYOND cache doesn't work. reinstalling BYOND doesn't work. Spawning them in the game world or assigning their ckey to someone doesn't work.

I've had this issue happen to me twice already, a friend of mine got it when I tried showing him SS13, and I've had a couple of adminhelps about it.

I did eventually got the game to work again, but I have no idea what caused it. Sometimes logging into the game a few days later works. Sometimes it doesnt. Sometimes it just starts working randomly again in the middle of a round.

This may be a BYOND issue. I got this happening to me again, and I corrected it by updating BYOND.
