Ok this is kind of ridiculous

I understand that Riot is very strict on leaving games. So strict that if you leave a game and it is completed, you will not get the rewards. But, COME ON. The link is the history of a game I just had. I went Wukong top and ,hands down, dominated the entire enemy team. My Final score was 28/6/7 which means I had more than half of the kills of my entire team and the lowest amount of deaths. They game stretched further and further to the point where I was scared if we would lose. But we didn't thankfully. The problem is that my game crashed RIGHT AT THE END OF THE GAME. I was salty to come back into the client just to see that I won the game but didn't get rewards. WHY. I essentially carried an entire team to get a win for them and me getting nothing. To make things worse. I couldn't get an S, so that was also a loss for anyone in my team that could benefit from the S rank.

Just to be clear, I am not mad that this happened. I could always grind up for what I missed. What I am mad at is the thought that you could COMPLETELY carry and be able to not get anything. I feel like Julius Caesar, getting stabbed in the back after raising a country to military victory. (I don't the history of Julius Caesar.)

What about you guys. Has something like this happened to you?
