...if you are OFFICIALLY still in a game, but got disconnected from the server you can go in the lobby and hit the "spectate"-button. The game will try to load you in, but instead of setting you as a spectator you´ll "merged" with your "old player entity". This is very useful as you can avoid that ugly Quit-> Wait for Network Connection->Start PA Launcher -> Hit Play-> Get in-> Get Logged in-> Waiting for Reconnect-Button to appear-> Hit Reconnect You´d normally have to do! Anyways, it would of course be better to simply have a "reconnect"-button in the game instead of using that bug...
It isn't a bug. I've not looked at it, but I would not be surprised to see the "spectate" button and the "reconnect" button do the same thing: Connect you to the game in question. The server of the game will then go "oh you're back", based on your name.
