Yorick's Damage Post Game is Bugged

Recently I played two games with a and I realized that his damage on the charts post game have to be bugged. When I looked at damage to champion it said that he did over 500,000 dmg to champions. Mind you in one of the games the Yorick was like 0/4 and in the other game he was 10/9. It even said he outdamaged me when I was playing (My score was 24/5/9). So I just wanted to let you guys know that his damage is bugging out when viewing it in the post screen. (That huge portion in the pie chart is supposedly all of 's damage!)
