[Gameplay] Thresh (Classic Skin) walk/run animation still bugged for several patches now

The classic skin for Thresh has had an animation bug for a while now. It happens when you pick up a soul while walk/running.

The right leg seems to disappear and the lantern turns almost completely sideways. All while his entire body seems to go semi-stiff and morph slightly.

I've seen this happen every time Thresh is played in LCS games as well.

Easily recreated in-game by just picking up souls while running. Does not happen on Championship Thresh, and I'm not sure about Deep Terror Thresh.
