I was playing in a premier draft with two losses and my connection dropped. I was able to reconnect before much time had passed, but instead of sending me back to my current game I was sent to the screen showing my current record and allowing me to start matchmaking for another game. I started a new game, which I won, but on exiting that game I saw I had received my third game loss (which I assume was from the game I hadn't been able to reconnect to).
