I just edited the oridinary CYS residue, removed the HG atom, and (I think)
modified the charges.

This will never work. A pdb file doesn't have any information about amber
atom types, and drawing in bonds doesn't add type information either. So,
nothing you have done would assign atom types. You could select all atoms,
then "edit seleted atoms" in the xleap GUI, and fill in the atom types by hand
in the spreadsheet. But my way seems simpler, especially if your cyf.pdb file
doesn't have hydrogens either.....
