Description of the bug:
While in First person, the body is aligned to the head's Y-axis rotation (looking left-right).

Aside from the above:
Occasionally the Third-person model only looks to the right, even when the view is to the left, which may mean an accidental absolute value.

Mod Version: 0.9

Seems like some config things reset.
