How about this:

  if you change a class-descriptor by adding/removing a field, make sure
you check all collection and reference descriptors to make sure the
indexes of the reference fields have not changed. This can lead to some
very weird placement of wrong values in wrong columns. In our case we
had a ref field being filled with the wrong value from the referred to
table.
