[Gameplay] Graves AA Bug

So at around 5 seconds you'll see that I attempt to auto attack the small creature beside the blue buff, the shot sound is made the gun kicks and the cooldown time is applied.

However no damage is registered, the shot texture is not there either, there is also no knockback.

I can't recreate this at a specific time it just seems to happen at random but I've had it happen hundreds of times and it only took me 4 minutes to recreate it this time.

Would really like to see this fixed as especially with someone like graves with an AA speed of only 0.50 that delay makes a massive difference in a fight.
