Darius champion bug

Whilst playing ARAM I was killed by Darius. I opened the "how you died" box and all of Darius' spells were invisible. The % of the spells were there and it said if it was physical or magic damage, but the icon and words were completely missing!!

I tried to print screen it but due to my duel screens it just turned out to be a massive mess.

anymore information about the bug, don't hesitate to ask :)
