Perhaps this is old news to others, but I just figured out that you can continue playing a scenario even after it is officially "over." I just played the Carolinas scenario with the new patch and wondered what would happen if I hit "Next Turn" after the victory screen popped up. So I issued some orders, hit the button and the scenario continued! Don't know how long you can keep playing, but it is nice to know that you can continue to play out a scenario to see how it goes.
Anyone know if this works with the full campaigns?
