[Gameplay] - Game Lagged out All Players

I was playing a Pre30 Draft game when my game got attempting to reconnect. (About 20 minutes in )(My internet was still working) I waited for about 2 minutes then closed the game and attempted to reconnect from the client. It didn't work so I sat there for about 5 minutes trying to reconnect. After 5 minutes, the game ended with my team's victory (we were winning) . I later learned in post-game chat that apparently the game had made all 5 players on the enemy team and 3 people on my team (including me) lag out. The remaining 2 people on my team had won us the game with no resistance.

  I have no way of recreating this bug because I have absolutely zero clues on what led to this bug.
