Yes, sorry, it's a bug - I also came across it yesterday trying to do
the same thing. Should be fixed in 1.4-151.
However, there are several features missing that are required to make
handling of R-free flags robust: in particular, if the R-free set is
missing reflections for which you have amplitudes, it will not fill
these in. Doing this requires refactoring some low-level code - also
a high priority for next release, but somewhat complex (since it will
also need to deal with flags assigned by thin resolution shells).
