I would continually run phenix.ready_set in this case - actually, if
you're using the phenix.refine GUI I think you can just click
"Automatically add hydrogens to model" and everything else will be
done automatically.  (If not, that's a bug too!)  Unless you are
performing neutron refinement or some very specialized high-resolution
enzymology, it is unlikely that you will actually care about
preserving the hydrogen positions from round to round anyway.
