Metal Bug?

The metal bug in question here is Mecha Kha'zix :^)

I got Mecha Kha'zix recently (when he went on sale a few weeks ago) and I've noticed a strange thing with it that doesn't occur on base or sand kha'zix. Sometimes when moving around with Mecha Kha he hunches over and stumbles around; basically he looks like a bumbling buffoon. I notice this the most when moving around with a speed boost (beginning speed boost, homeguard, scuttle shrine) and also sometimes when walking through brushes (normally he would tuck his arms in but every so often he does the tripping thing). I'm pretty sure I've seen him do the stumble thing other ways as well but I don't know how to replicate it.

However I do know that when I got Mecha Kha while he was on sale, his claws were bugged (get it?) for a day or two (they always displayed the evolved version), I remember seeing that in the last patch notes. So it might just be that the skin still has some quirks leftover.

It doesn't affect gameplay, but visually it makes Mecha Kha look like a ghetto robot. I'm also not sure if the "stumbling" can be seen by other players

Edit: Also sometimes he crooks his head to the side and it doesn't return to normal for a few seconds or it glitches in between the two (regular and crooked). I noticed this as well on the lolking model viewer for "Run Haste Fly" and "Run Haste"for all of his models so this might have always been a thing that I've never noticed <_<
