During rigid-body refinement, the bonds/angles/dihedrals/nonbondeds
to the non-refined sites are not restrained. This could seriously
mess up the geometry.
In addition, rigid-body refinement and individual refinement will
only run alternatingly.
I'd be surprised if the parameter combination above did much good,
but you never know before you try it.
Simultaneous refinement of individual sites and (small) rigid bodies
with full use of restraints is on our long-term wish list.
