Idiot's Guide to Making Custom Maps?

[Zylithan]

I only have single pixel white dots now.

My problem is that when I click (in game) in a space that looks like part of one province, the computer selects a different province. Now, if I click right on the flag, I always get the correct province. But for long or irregularly shaped provinces (see my attachment) this is a problem.

Now, maybe this is how the game is... where you click on the overland map, it just selects the closest white dot. But I have never had this problem when playing a map I did not make personally. Then again, most provinces are roughly spherical in the maps I have played. So maybe this will be a problem on any map with dramatically nonspherical provinces. (This is my conclusion based on what Gandalf said above.)

The image I attached isnt meant to be a real map, of course, but it is a tool for explaining my problem, and for me learning the system.

Thanks!
