[Gameplay] Graves AA Bugged

Alright, I am almost positive that I'm not imagining this. It is difficult to tell due to how subtle it is, and how occasionally it happens (not very).

I've noticed on several occasions that Graves AA would play the animation, consume ammo, but not deal damage (didn't even register as 0 damage) or activate the knockback (in the case of being used on minions/monsters).

I am unsure how the people I've noticed or myself are getting this bug to occur. I've noticed it more often when going from Auto Attack to End of the Line very quickly, but I'm sure it isn't JUST us canceling the AA since the ammo is consumed despite playing the animation out fully.

Again, I could just be imagining things. I am fairly sure I am not though.
