When using a custom skin in version 0.0.7a, if you attempt to offset a base body part, such as the head or arms, any offset in the x or y planes is constantly applied. This results in the, albeit hilarious, effect of said part flying off into the sunset. This persists even if you change the skin.

Steps to reproduce:

1. Load up a modpack with CustomPlayerModels on Forge v35.1.28
2. Create a new custom skin on 0.0.7a
3. Attempt to offset a base body part in the x or z planes
4. Say goodbye to the part

After a bit of testing, I've noticed a few peculiarities:

1. Arms are working as intended i.e. not flying away.
2. Legs only move constantly in the x direction.

Hope that helps.
