sometimes, when i am dead and spectacting: i hear the clock sound (generally suppose to happen when you have 10 seconds left on your shot timer) I think it happens in ALL SHOT (or team shot) when those that are alive take so much time to shoot that you WOULD have had 10 seconds left if you were not dead (i Believe that is why I don't hear it on one shot, because the game knows I wont shoot, but in all shot it thinks I'm still on the team of shooters) Actually i just heard in it an all shot, FFA, rebound game less than a second after the last damage finished... so at least in one circumstance it is just playing at an incorrect time (i'd say randomly, but nothing in computer bugs is really random... there is a reason, we just don't know it)
