Fixed it!! I had to delete the figure and reload her,  and reapply the pose.  It worked, but I was hoping to avoid having to do it that way.  Turns out those we're the onyet two scenes that got messed up.  I have hundreds of scenes saved as pz3 files, I opened these two consecutively and assumed they would all be like that.  Turns out these we're the only two. I would still love to know what caused this so I can avoid it in thee future.  Back in business at least!  Thank you all for the helpfully suggestions.
