Yorick Statistics Bug (All the True Damage)

So, I just played a game as Yorick, and was doing pretty well if I do say so myself. However, the end of game screen/statistics blew my stats way out of proportion. As seen below:

I'm not sure exactly how to reproduce the problem, but it seems to include the damage taken while in yorick's ult into the end of game statistics and match history. When you die as yorick's ghost you take a lot of true damage (i think it's 100k per ult.)

Edit: So, I'm not sure why my links/pics aren't showing up. But they were just screenshots showing the extra numbers in the match history.
