Game crashing

The game keep crashing not all the time but just at random times.

The match is already over and I get a loss + penalty for 5 games for 'leaving' or being reported by other players.

I'm really angry because it's not my fault and I get 'punished' for 'bad behavior' and now I'm on a 'lower priority queue' which just means I have to wait 20 minutes every game every time I want to start a game.

To anyone who cares, thanks for reading this. And to riot please look into this.
