[BUG] Ender Dragon model head and animation

[Nuanulla]

Version

• [x] I am using the latest version of CEM

Describe the bug

Ender Dragon head bone is further from the body bone than it should be. Separately, Ender Dragon animation doesn't seem to be working (for clarification, I'm using a sin() expression. Is this supported?).

Expected behavior

Head should be closer to body. See images.

All the animation expressions are supported, including sin(). Could you include the .jem file please?
