My example does not introduce new [atomtypes] into the force field.  Yours does. 
  Hence your #include statement for lig.itp needs to precede any [moleculetype] 
defined in the .top file.  The simplest way to do this is just to move the 
#include statement immediately after the #include for the parent force field.
