I've built a second Army (Army of Potomac) with Butler who was moved to NY from Ft. Monroe in view of a Dec 61 invasion of New Orleans.
Butler surpassed Freemont and that's ok, however, I noticed that the HQ unit was not assimilated to the general (like it happens in AACW) and I also noticed that Freemont can still be named Army Commander (though he would bypass Banks now) even though he doesn't have the Army HQ with him.
Question is: This is OBVIOUSLY not working as in AACW (you can only form Army in presence of *** AND an Army HQ unit) but is this intended or is this a HUGE bug? If it's WAD what's the purpose of the Army HQ unit in CW2?
