[GAMEPLAY] Anivia Flash Frost Disappears on Summoner's Rift

This bug has been in the game for months if not years and is unfair to the loyal Anivia base. I notice it at LEAST once a game in which i'm in mid lane. When she launches her Flash Frost the animation will work, you can see the frost and damage hitting enemies, but you CANNOT SEE THE PROJECTILE. I know i'm not the only one to notice this, and it makes effectively bursting her Flash Frost to get full damage because the summoner needs to see where the projectile is to activate the ability again for double dmg. Please, please, PLEASE fix this. I main Anivia and this has lost me more kills than i can count without even thinking of how fewer minions i have killed because your projectile layering isn't set up right for her and the projectile drops below the ground layer while the damage is still in place. I would rather it just not work at all than have the projectile vanish.
