Yorick Damage dealt in post-game stats is obscenely high (Client)

I realize that this issue has already been brought up, but I am unsure of the procedure on reporting it myself, so I am simply posting a new thread. I just played a game against a Yorick, and in the post-game stats screen his damage dealt to champions read as 517,476, which seems impossibly high. Aside from Udyr, who had damage dealt of 112,671, everyone else had damages ranging from 10,000 to 30,000. I have a screen shot of the post game chart and the overview to verify this, and can send it in, if requested. Also, if there's any other information that I might have forgotten, or might be helpful, let me know and I will do what I can to answer it.
