[GAMEPLAY] Aatrox stuttered walking animation

Occasionally while I've been playing Aatrox I've noticed that after doing a quick E > Q combo his move animation stutters(more of a visual than his movement). I've been able to recreate it a few times pretty easily but there's been some times, in the same custom, where it just doesn't happen at all.

Sidenote I've also noticed that after using Aatrox's Q he starts auto attacking immediately and I don't know if I've just been blind and it's supposed to be like that or not.
