Right, I'm working on a mod that adds some content to the stock map's central african region. I've tried adding Lake Chad as I believe (but the map is skewed and difficult to exactly pinpoint for me) it should be at the very edge of the map in the south. I've got the "province" for the lake working fine, it functions like it's a lake in game, but unfortunately when I attempt to edit the stock terrain map it crashes the game. I've used only the colours sampled from the rest of the map (the stock colours), using a solid pencil tool, but I'm really working in the dark here without any prior experience nor knowledge (couldn't find any tutorials on editing the map), so I'm likely doing something completely wrong. If anyone has any ideas that could help me out that'd be great, and just in case, I've included the editing terrain.bmp here for you to take a look at and see if i'm doing something wrong. (for the changes, look to central africa)
