You're talking about the FIXME on line 1449? That should only be a problem
if the mapping between your Mesh's node numbering and Exodus's node
numbering, as stored in the libmesh_node_num_to_exodus, is something other
than the trivial off-by-one map.
I don't know if the presence of NodeElems, which are treated as Elems (?),
would have an effect on this, but I suppose it's possible. What is the
error message you're getting?
