[GAMEPLAY] Nunu's Snowball visual bug

So this bug is actually really funny, but I figured I'd post about it nonetheless. It was during an ARAM with a Nunu on the opposite team, the very first snowball they threw down lane just never disappeared. It was only visual, the animation of it spinning in place was there for the entirety of the game. It was only visible from our side, the enemy team couldn't see it.

Here's my friend and I dancing with it. https://cdn.discordapp.com/attachments/262879260933357568/608118461956358144/unknown.png
