It is not necessary to exclude residues when using the torsion angle NCS restraints, even if they are in different rotamers. The potential used to restrain related torsions automatically shuts off in cases where the related torsions are sufficiently different, such as for different rotameric states.
One possibility here is that the sidechains forming crystal contacts are in non-rotameric conformations - in this case, wouldn't the rotamer correction try to adjust them to agree with other chains? -Nat
