I ran into a situation where, playing as Allies, I took Copenhagen before the Germans could. This may be resolved in a new version because I know you made Copenhagen easier to take for the Germans, but what happened was that they would send a Pz Corps in, kick my troops out to the north, take the city, then withdraw. I was then able to walk right back in, causing them to redeploy the Pz corps. The end result was that I was able to hold France. Paris was never captured.
Even if the Copenhagen problem itself is solved with the map redesign, it still serves to highlight a problem with the AI assessing threats to territory it wishes to control.
