When I wear bit armor on my head, the armor doesn't move when my head does as seen in the pictures below. Any ideas as to what is causing it to happen, or is this normal?

Forgot to mention I'm playing 1.10.2, and that any chest pieces I make render smaller and inside my player model.

I'm assuming this is another instance of incompatibility with More Player Models.

This should be fixed as of v3.3.0. Let me know if you run into any problems.
