The -ci option should be used in conjunction with -nmol, and the configuration 
contained in -ci (I believe) cannot contain multiple molecules.  If you want 600 
molecules/atom to be inserted, provide a configuration of a single molecule/atom 
and specify -nmol 600.

With respect to the topology not being updated, that is to be expected.  The -p 
option only works for water (unfortunately).
