Visual bug with PROJECT: Ashe Volley [Gameplay]

I've noticed that whenever PROJECT: Ashe uses her W, the arrow particles seem to stop just short of the actual hitbox, which means that anyone on the edge of the hitbox will look as though they will not get hit, then will. This only applies to the PROJECT skin, and all the other skins that I have seen (base and Heartseeker) actually have the arrow particles go past the edge of the hitbox (they don't do damage past the range of the actual ability). This happens 100% of the time, and you can see this easily with target dummies in the practice tool.
