Humanoid animation variable not updating

Hi there! I’m gonna make this as quick and short as possible:

Animation Combo_03_01 sets the rotation of the ChestReference gameobject throughout the Animation.

When the mask is set as such, the rotation of the ChestReference gameobject is no longer being set:

I’m curious as to why. The ChestReference gameobject isn’t a part of the Bone Structure. This is the structue of the Player object:

Any suggestions or ideas as to why this is occuring? Thanks!

Here’s how it looks like in action: (Look at the Spine & ChestReference rotational values)
