My free time is getting smaller so it's becoming harder to help you here, but at least while I talk to my gf on the phone I can update ships as this is easy to do and don't take any of my attention (so she doesn't shout saying I'm not listening to her
)
I intend to complete the British Navy later today and then start the American Fleet. I'll focus on the original AND civs for now while we can't put the Mega Civ Pack to work as intended. When I get more time I'll check the Mega Civ Pack compatibility.
BTW the russians have made Conway's All Fighting Ships book available in pdf on the internet, so I already got it to help my research.
And I need to know which SVN are you using to make the scenario. I'm not having time to see the changes ppl are discussing here so I stopped upgrading in rev 739. I would like to have a copy on the svn you're using so when you make it available I may test the map
EDIT: Small update on english fleet
