Fight Submission Timeout

Ran into this for the first time, not sure if it’s new or not but I’ve not seen it in a year of play. Decided to set my phone down and take care of something while waiting for my GA fight to finish out so I could preload intelligently, only to come back a few minutes later than expected to find that the fight was automatically forfeited. Who in their right mind thought that was a good idea? God forbid I have to step away from the game for longer than 4 minutes. Any hope of full cleaning is gone now, so thanks for costing me and god knows how many other players their matches with this idiotic mechanic.
