Various animation errors! [Mod support!!]

Like a handful of other animation errors I've reported this aren't all that easy to get to happen in the base game but for modding sakes it'd be a wonder if these could be fixed. 
A handful of animations are currently missing or incorrectly animating the "swap_face" symbols. This leads to errors with mods adding in accesories that use swap_face!

A lot of characters customs idle animations are missing these symbols entirely.
Warly has them but they vanish at the start and end of his idles.
Willow also has them but they don't follow the face in the animation, instead staying in the middle.

I ask for these to be fixed as a friend and I are currently doing a huge mod collaboration that implements glasses (as shown) for characters to wear, and it'd be wonderful to have these animations touched up since editing animations is out of our hands. I appreciate it!
