Yorick Insane damage bug
This bug occurs on Yorick although I don't know how to produce it or if it is just a continuing bug with him but at the end of the 24 minute normal mode game I checked the damage I had done overall and to champions and was surprised to see that I had done 111,400 damage to champions and about 200,000 damage overall. I never hit anything close to that in the game and as you can tell in the match up link I provided I only had 3 kills and I never did any high amounts of damage to minions, monsters or champions so the damage was miscalculated by the system I presume to what it actually was.
Also an edit after checking more statistics it appears that the miscalculating dmg is coming from Yoricks true dmg from what I see on the statistics page where my total true dmg dealt to champions was 100 thousand true dmg
