Void Bringer Illaoi not animating properly

Just had a game where: E: Test of Spirit wasn't animating when Illaoi was not visible (fog of war etc) P: Prophet of the Elder God; some of the pillars spawned where untargitable for a few seconds after spawning, and their hitbox was missing.

Please look into this as it made her really frustrating to play against her, had at least one death because I couldn't dodge an attack created by her passive :(
