I have a pen I have rigged, and almost everything works great. The problem is the eyebrows, both of which have three joints. The eyebrows and joints are part of a group that is parented to the main body. Now, without the rigging, the eyebrows move as the rest of the pen moves. However, when I bind skin, and then move the pen body, the eyebrows veer way out in space, not remaining attached to the body (the joints stay with the body, correctly). When I delete history, it solves the movement problem, but the joints are no longer connected to the eyebrows.
I would appreciate it if somebody could take a look; the file is attached.
