You left out key information: what are exact commands you used to "build the
complex"? Somehow, you probably loaded a file with connectivity information
in it, that asked LEaP to create the Zn-S bond.
Amber's advanced tutorial 20 goes over the procedure for simulating zinc ions
both with and without adding bonds to neighboring atoms. You might look there
for clues. It sounds like you with to use the "nonboded model" described
there.
