The error comes (more or less) from ffbonded.itp, because grompp is looking
through your topology for all the bonded interactions it needs, and in this
case, can't find one.

All of this is critical information that you left out of your original post,
hence my assumption that your issue could be easily solved. When reporting a
problem, please be as specific as possible! If there is a problem with our
latest parameters, we need to fix that, but I don't yet have enough information
to tell you what's wrong. grompp did, however, give you what you need to figure
it out. The fatal error comes from line 23560 of the topology file. What is on
that line? What are those atoms and what are their types?
