hi. it is turn 3 and I (CP) want to start promoting army commanders to GHQ rank (army group). i can't promote any German 3-star leaders (even though the 'form GHQ' icon is highlighted) without incurring a penalty, because Austrian 3-star Potoriek is the most senior general. But his 'form GHQ' icon is greyed out. He is adjacent to Belgrade. Why can't I promote him to GHQ? He is holding up all the others.
As an aside, isn't there a rank missing? Shouldn't German OHL and Austrian AOK be a rank higher than 'GHQ' (which seems to be army group)? They were not army group commands but army high commands for Germany and Austria respectively, higher than army group.
