Are you sure these are real FP=0 or reflections which werent measured
but have been added for completeness of the h k l list.
The check is whether the SigF is also 0.00 - in that case they are
genuinely missing..

Excellent point and no, these are not missing reflections. SigF is not
zero. Also, if I am not mistaken, missing reflections in the MTZ format
are recorded as NaN.

This does sound like a bug. If one of h,k,l are zero then the reflection is
centric in P222 so the truncation will be different
I just ran a test on an orthorhombic dataset (P212121) of mine and I do indeed
see some strange F=0, sigF0 reflections, but in Charles Ballard's
development version
I observe under some conditions that ctruncate sets some reflections
amplitudes to zero. AFAIU, this should not be happening as even
negative intensities (there are none in this particular dataset) should
produce FP0 upon truncation.
66 out of ~23000 reflections are zeros after ctruncate is
