I get all of these replacements but they don't get used. I'm assuming units on depots are somehow repaired but I don't see it happening? In the end, there are dozens of unused replacements.
Some ports are blockaded but there are no enemy ships, units, or ice blockage?
In the Seven Years War campaign, what does one do with the Cuba invasion force? The fleet blockades Havana until supply runs out but the ground units don't do anything except repeatedly fail to retreat (but nothing adverse seems to happen?)? Also, just curious why Iberville Parish is a strategic location? It seems Pontchartrain or New Orleans would be the target in that general area. I don't think Fort Jackson (a predecessor, anyway) was built yet and even if there were already plantations there, wouldn't New Orleans still be the key?
This is just a comment but I find it strange that a supply unit can block an entire army from moving into an area.
Is there a way to evacuate troops if there is no friendly port? Louisburg comes to mind. Lost a lot of good troops there when I couldn't evacuate them when supply ran low.
OK one last unimportant thing about the map: as someone who grew up in Harrisburg, PA, I'm fairly sure the names are reversed for two nearby areas. Harris Ferry should be on the east bank and Cumberland County on the west bank of the Susquehanna River.
Enjoying the game; just have a lot to learn still.
