I meant, could some of the tiles set to the ground type "sea" become part of a province that isn't "The Sea"?
Anyhow, thanks a lot.
The main reason for this post is a major cut-down on what I am going to do with this mod. My original plan was to overhaul Britannia, AND make sweeping changes to nearly all the other factions, and massive overhauls of the campaign map. But there is a problem.
My girlfriend doesn't like me spending the amount of time on the computer required to make this mod, and it's not the only thing I do here either. So I need to backtrack, slow down, and settle for less.
I have almost finished this mod. I am just tweaking the map of Britannia again and re-ordering the unit roster, rolling back the changes to Noricum and the Po Valley, adding two other provinces (Corsica and Scandia), renaming Gaul to "Celtae", Spain to "Iberia" and Britannia to "Pretani", and then I'm leaving this alone indefinitely. Perhaps I'll come back in the future, unite the Romans, make all factions playable, and do some of the things I'd planned; but for now, I can't.
Thank you all for your help. I will cease to update this thread with posts, and instead just update the first post with an overview of the changes I've made when this is done, until the mod is up for download.
