[GAMEPLAY] Vel'Koz Animations Bugged

So I decided to go Vel'Koz adc with some of my friends in the new patch and I noticed that the animations were just... broken. When he moves or autoattacks, sometimes he will freeze but the autoattack particles will do their thing. This occurs with crits as well. I don't know what triggers it but am assuming that it is a bug with some of the champions whose sizes were changed (Vel'Koz was reduced by 5%). This was not just on my client, as the enemy support asked in /all chat what was up with my animations.

I suppose all you have to do with the bug is play a game with Vel'Koz. If you want to see the different particle effects at work while the autoattack animation is frozen, buy a crit item.

I have no videos or screenshots of this happening, and it happened to me only once after I updated to patch 5.23.
