Greetings!

I had encountered a problem while editing my map.

After developing a sudden interest in Carthage and all things related Carthage I wanted to add those two funky looking lakes southwest of Tunis already present in Mundus Magnus just for the sake of it (Chott el Djerid and Chott Melrhir, I guess).

I made a neat copy and paste from Mundus Magnus, saved everything and loaded the game.

Everything seemed ok, but just for one turn. Soon I found that something went wrong with the map generation. The port at Lesbos was erased and there were a lot of random water tiles where it was supposed to be earth, like in between Athens and its port.

But what it's worst: After restoring my old map_regions.tga, map_ground_types.tga and map_heights.tga (basically, everything) the problem still subsisted. I could only solve this when I copied map_heights.hgt from a very old backup.

Long story short: finally I could modify map_types.tga and map_heights.tga to add those two lakes and keep the regions in my map just as I want, but only after generating a proper map_heights.hgt file, thanks to this tool from alpaca:


So it seems map_heights.hgt is not that useless after all.
