Aphelios Crescendum + R Spam break

I wanted to try Aphelios in the practice tool and looked into things that he can do so i noticed that the Chakrams you gain while ulting in Crescendum are stackable. I stacked them to 400 and then Aphelios started moonwalking, never showing any other animation. Minions that died just showed up as 1 health but arent actually there and so on. I was using the Aphelios skin just in case that matters. Sorry for bad english.
