I've been looking at the E3map, and it is awesome. Would add a lot to this mod if you can get it working.
Being a noob modder myself, i had a look at it.
I've come as far as getting the map working with all provinces in 1 nation. The idea was that, once that worked, I could just release all seperate nations and start adding the leftover extra provinces to their nations in the game, ending up with a saved game with all the correct nations. After that, copy-paste from the saved game to the scenario files of the countries. Offcourse it didnt work. Liberate country button greyed out. And it was probably going to be more time-consuming than anticipated.
What is the most work? Is it just about copy-pasting the province numbers from the E3 country files to the country files in your mod? Cause if that is it I don't mind helping out a bit.
