Jarvan Auto Attack Bug

I was just in a game, playing J4 obviously, and about 50% of my auto-attacks were without an animation. To clarify; there was zero auto-attack animation when i would attack a minion/monster/champion, however it would still deal damage and get CS ect. As i stated in the first sentence; this bug occurred for roughly 50% of my auto-attacks in the game. I have not gotten into another game to see if the bug was still occurring, but that is also because i do not want to continue playing J4 with this bug active. I don't know if it makes any difference, but i was using the Commando J4 skin.
