Occasionally, we (my PBEM partner and I) an airplane in an army/corp HQ. Usually it moves on to an air unit attached to the HQ..but annoyingly, it prevents the HQ from moving anywhere other then an adjacent town.
I think I read somewhere that you were going to fix this, but I cant find the reference, so if you are, forgive me for repeating it...
If not, can you avoid 'noticing' the airplane when calculating how the HQ will move?
