Blackthorn Morgana Q Invisible!

I just played a game where Blackthorn Morgana's Q was nearly invisible. At the start of the game it was fine but about halfway through my buddies and i started noticing it. It looked like a tiny light grey tumbleweed flying at you. Almost as if the actual missile was invisible and only its shadow was showing. It was VERY hard to see and had an impact on the outcome of the game. Not sure if it's happening on any other Morgana skins. But it is definitely happening on the Blackthorn one.
