Dear Dr. Blaha
I act as you said, but the problem "LAPW2' - semicore band-ranges too
large, ghostbands" exists again!!
LO for N-2s orbitals in case.in1c were removed, but it worked just
for rkm=6 (with or without LO for N).
I tried your way with changing rmt of atoms but the problem remained.
I tried a normal scf with RKm=7, from the beginning, at a different
directory, but nothing was changed. Just, crashing LAPW2 is postponed
in some more cycles.

I tried your struct file, converged with RKM=6, saved, increased RKMax
to 7 and continued with run_lapw.
No problem. As expected with your RMTs rather small change from 6 to 7
and quick convergence.
You must have changed something else, like mixing a density with
different RMTs, .... ????
