My partner shuvashish76 disconnected while their clock was ticking and was closest to flagging. I see their clock gets to zero but the game continues. then my opponents (tony) clock finally got to zero, but since they are online the timeout was detected and my team was declared winning. Log does not contain "Flagging from serverside" line indicating it ever detected the timeout
