I believe this is fine since I think xleap writes out pdbs with its internal
numbering rather than the numbering in the original pdb. To double check
though you should set write_pdb=1 in the qmmm namelist. Then when you run
your QMMM calculation you will get a pdb of the QM region, including link
atoms, which you can then visualize to make sure you got what you expected.

Good luck,

Ross
