It is not uncommon to see things like this. You probably need to examine
different starting configuations, maybe different parameterization of the
ligand force field; maybe just recognize that biomolecular simualtions are far
from perfect.

Of course, there could be errors in your input or in the programs themselves,
but it generally takes a lot of experimentation and debugging to find these.
