I can add a magnet to a body part and customize the "zone". "base", and "mag" and all three pieces will move with the figure. When I save and load back this set, only the "zone" stays with the appropriate body part and the "base" and "mag" stay in a fixed posistion. They still deform the right body part but they are just "hanging" out in space. What am I missing? Sheldon

Check the parenting properties of each part of the mag deformer. It's basically just a prop and can be treated as such. Make sure the base is parented to the bodypart; the mag and the zone should be parented to the base.
