Yorick - Damage to Champion bugs
Games with Yorick in them misreport damage to champion stats at the end of the game. I've only seen it happen on LotPK so far. Last game, the end game stats displayed Yorick as having dealt approximately 200k damage to champions and two of his team members as having done about 100k each. For reference, the highest damage to champions number on our team was about 20k, and we won that game by a pretty large margin. I'm not sure exactly what causes it but I think it has something to do with his ultimate - the other game I saw this happen, only Yorick had an inflated damage number but he only ulted himself that game.
