Well, the only way I know of to get to the attribute in question is to use an UnHide Dials python script.  I've tested that out and by unhiding the dial in question, I can also correct the problem.  In the hand it is an attribute called INVThreeFinger, and in the neck it is INVHideNeck.  if it is at 0, the body part is locked, and at 1, it is unlocked.

Just exactly as RHaseltine indicated.

So I have two ways to fix the problem now, the first being just to not Zero the figure, the other to unhide these attributes and reset them to 1.

I wonder too why the lock is at 0!
