Ranked Issue

While 3 stacking in a ranked game we were all 3 simultaneously lagged. Me and my friend disconnected at the same time, tried re-joining and received a "the match has ended message." This is despite my third friend remaining in game. About 10 minutes after disconnecting we received a matchmaking penalty and lost 100 rp, all out of our control. 

P.S: The pathfinder buff is immaculate
