Moving settlements

[pietomb]

Hi All,

I'm new to modding, just trying a few bits out. At the moment I'm trying to move settlements and ports, I've moved the single black dot for towns and white dot for ports in map_regions.tga, but when I run the game nothing moves.

Any help would be greatly appreciated, thanks!

EDIT: I have found I can edit it once, but then it seems to use a map from a temporary file somewhere, not sure why it's doing this.
