Another series down the drain

2 complete AFK's, as in they never moved, never connected, just were not in game... and of course we lost. (other team also had an afk...) Anyways I've heard a rumour that there is a save protection? What more needs to go wrong than 2 afk's b4 your series gets saved? Because after the loss I surely was "Unsuccesful in completing my series" or whatever... Does save protection exist?
