Yorick's Q has a visual glitch when combined with Iceborn Gauntlet

I sadly do not have an image of this happening, due to trying to play the game at the time and not personally knowing how to take a screenshot, so if anyone else could test this again for me to not only confirm that this was a one game occurrence and also get a screenshot, it would be appreciated. The issue at hand involves new Yorick and his Q. When he has an iceborn gauntlet and proc's it with his Q, it has aoe damage, which can potentially kill multiple units with the Q. However, when the other minions (that weren't autoattacked directly) are killed by it, you are rewarded with a grave to summon ghouls, but the graves are invisible and can't be seen by you or the enemy. These invisible graves are either an issue due to getting extra graves that we should not be rewarded with, or due to a visual glitch that prevents these extra graves from being seen. Either way, this is a small bug that I'm sure riot would want to patch here soon. Good luck!
