FYI, best to keep these sort of discussions on the emailing list. That
way information is there for others to see and refer to in the future.

I have no idea about the pull code, but assuming that it does have
issues with the PBC ....
Then after the system has been solvated I would then move the molecule
of interest to the edge of the box. Do that by centering the box (using
editconf -c) on a water molecule somewhere in the system such that the
centering moves the molecule of interest back to the side. Suspect that
you pick the water to use by visualing the system after solvation with
something like VMD, select a water molecule on the center of one of the
sides of the cube and try that.
