Difficult to answer without the data. I you agree to send me your data, I would
be very interested to look at what you got...

As I said previously, adding restraints can generate very weird charge values...
The fact that all is done automatically in R.E.D. allows to study this problem
more easily: We will work on this particular problem with the handling of
intra-molecular restraints in R.E.D. III to make the detection of these types
of problems more simple. Regards
