Two Games at Once Bug

Hey so I played a ranked game on March 28th where all of us in the loading screen bugged out and we ended up having two games open at the same time. There was one game I was in, and then another game was loaded up of the same game. We won the first game, and the enemy team had one guy pushing down mid in the other game, and they won first. After we won the game we were originally in, it said we had lost and I lost LP. If you look at my match history it says Victory, 1-0-9 Ezreal with a few items, but if you click on the match description it shows my build from the other game. We essentially lost a game we could not do anything about. Every member of that game experienced the same bug.
