Let's try to get as simple a test case as we can. Can you load just the
mol2 and frcmod file for a single BF4 molecule (nothing else), and then save
the prmtop file?

Compare the files you are using to the "bf4.mol2" and "frcmod.bf4" files
that are in the tutorial. If you can't get this to work, give the full
(exact) set of tleap commands that you are using, along with any input files
you have.

I bet that once you see what is going on for a single molecule, you will be
able to create more complex mixtures.
