I think we will need some more information. First, see if there is a
SOLVENT_POINTERS section (also an ATOMS_PER_MOLECULE) section in your prmtop
file. If not, we need to know exactly what commands you gave to leap,
especially for the "solvent this unit with isooctane) step. Also, please
indicate which version of the code you are using.
