I've seen this happening to water molecules as well (in a somewhat unpredictable fashion). In the latest refmac versions, you can try harmonic restraints, although these will only slow down the atom drift, as the target position is updated every cycle. Perhaps you can use distance restraints agai

[ccp4bb] refmac low resolution REMARK

2012-01-01 Thread Bernhard Rupp (Hofkristallrat a.D.)
Dear Developers, it seems to me that at least Refmac 5.6.0117 does not report the actual lowest resolution used in refinement, but instead the lowest resolution of the hkl index range generated by the default cif import script instead. REMARK 3 DATA USED IN REFINEMENT. REMARK 3 RESOLUTION
