no loss prevented?

Just had a game where our team and the enemy team were randomly dc'ding/rc'ing all match and having horrible ingame lag, it cleared up the last 5 minutes but it was too late, half my team was so desynced they didnt make it back in before it was over. When the game ended, no loss prevented. This was no client side lag, this was everyone in the match seeing it, so what gives?
