Graves auto bug

we were 45 mins into a game and the enemy graves team just got baron and then every time graves autoed his attacks would shine a super bright yellow that took up 3/4 of the screen in a cone shape, everyone in the game saw it. this is a gamebreaking bug because no one could see any skillshots and so ori's ball went into us and killed us and we couldnt even see because graves auto kept flashing this bright yellow light. https://gyazo.com/51b1f8f2cd63a2d1cee5012088a472f1
