Snow day Ziggs [GAMEPLAY}

I was playing snow day Ziggs and about half way through the game my snow balls (Q's and autos) became invisible however the particles that followed the main projectile were still visible, I am unsure what caused it. I was playing with friends and they said that they couldn't see it either. I only did this once because I wouldn't want a game-breaking bug like that to be "abused". Not sure if this is relevant but this is my build order
