No exp/honor/champion mastery

No one on either team at the end of the game got any exp.

Based on how I did that game I'm pretty sure i would have earned an S or S+ and that would have given me my last token for level 7 mastery.

I'm not sure what could have caused it. Nothing special happened that game, and I did not see any other bugs during that game.

I'm not sure how to check the grading for a game, but if I was supposed to get the token, is there anyway I can get it placed in my loot?
