No. It just means that a molecule that has moved outside the periodic box
on one side was translated over to the other. (Not really translated, but
when one molecule moves out of a specific 'unit' cell, a periodic image of
that molecule moves into that cell on the other side).

This is not an error, and is completely normal when iwrap=1.
