Today in alt shot I was brought back to the lobby when someone discoed, but I was not let in. I restarted browser, clicked "Continue game" and pressed the button - nothing happened apart from that the "Timeleft" counter stopped. I waited 15 seconds. Restarted browser again and the same thing happened. I switched browser (to Chrome) and the same thing happened again. After all time had run out I got the "Your team lost, did not return in time".
Annoying. And we were in the lead :)
