This should never happen and now I'm confused myself. To find out what 
is wrong, I need to reproduce it on my computer. Is it possible that you 
send me the data and model along with the exact command you used; I 
promise to keep it confidential. In this case I could have a closer look 
and tell exactly what's happening.

This is not surprising. As I wrote in my previous email in group 
occupancy refinement you refine one occupancy per group of atoms and 
this occupancy is not constrained, so it can refine to any value that 
the data suggests.
