Are you sure this is really a "problem"? Finding unexpected ligand
conformations is one common goal in running MD simulations. It's not clear
(to me, at least) from just looking at the ligand snapshots, whether or not
something is wrong. You should examine the protein-ligand contacts, and
visualize the pathway going from early snapshot to the later one; that might
provide key information about what is driving the change.
