Heimerdinger

I played 1v1 on howling abyss with my friend using Heimerdinger and for some reason the turret kept shooting at him exen when he wasn't in range. I seen it several times before, once it was going haywire by red buff on the rift and another was playing as jax and Well out of the Ulted turrets range but the animation was still firing at me without damage. Only way I seen it fixed so far in game is if the turret dies or is recycled by a new turret Could you look into this?
