BTW, do you mean 2Fo-Fc map, not 2Fo?  And what exactly you mean by poor
density?

Don't know if the box size can be changed, but if you want to omit just
the ligand, follow Jacob's suggestion - omit the ligand and run
simulated annealing to remove bias.

In theory, the observed behavior suggests model bias.  What's the
resolution?
