Pose with transforms cleared is not same as rest pose

Hi! I’m having trouble with a rig (I’m using the pitchipoy rig of the rigify add-on). The rest pose looks correct, but a non-rest pose with all bone transforms cleared does not look the same. I have checked for hidden bones, bones on other layers, and there are no shape keys. I really have no clue why it behaves this way.

As you can see it’s only the arm/shoulder and one bone in the neck that changes. Interestingly, the IK hand bone does not move when switching between posed/rest, though the model’s hand does.



Any help or insight is greatly appreciated!
