Hmmmmmm, oh dear.....



Spoiler Alert, click show to read: 

It sounds like you've broken more than one thing in there if it's affecting so much.

If you are adding provinces/moving a campaign map you will need to include:

LUKUPMAP (and hi-res copy)
MINILUKUP
FE_MINILUKUP

In the startpos you must change: DeclareLandRegion, DeclareSeaRegion, SetNeighbours, SetBorder, SetAttributes, SetOrigin, SetPort, SetCastle, SetRegionRebels, SetTitle

You must also make the appropriate changes in your Faction_specific and Region_specific files, plus names.txt

That's all I can think of off the top of my head, but I'm sure there's more....

To be honest, your best bet now is to delete it all and re-install and try again from scratch, and have a CLOSE look at how other mods have instituted new maps. Even better, set it up as a sub-mod with its own textures sub-folder structure, then you can make changes without breaking your original. As I've said elsewhere, changing the campaign map is the most far-reaching mod you can make, as it has impacts everywhere in the game.
