You cannot build the two end states independently. All atoms, except the
ones in your scmasks must be identical in their starting positions and
order in the prmtop. It may be easiest to built a single pdb-file of your
system with water and ions and read it into leap twice, just changing the
residue name or something similar to build V0 and V1.
