Design the smallest test case possible, ideally just a single residue that uses 
your atom types.  Verify that you get the same error.  Then post (ideally) the 
coordinates, topology, and any force field files (file sharing links; the list 
does not accept attachments), or at minimum, the bonded section of the .top that 
is problematic (using grompp -pp here can be very useful, as it will explicitly 
put in the parameters so we can see what is going on).
