Hello Georg,
"c1=Q Kg2 cxa3 a8=Q axa8 Kf1 axa2 "
I think it's not a problem of "illegal" moves.  It looks like a
"display/printout" problem to me.  For instance the "cxa3" is probably supposed
to be Qa3 and "axa8" is QxQ and "axa2" is Qa2.  Probably an easy fix for Ed.  In
fact I have seen this before in earlier Rebels.
