Disregard what I wrote below. I put the Bvierra map folder inside of the C1 folder which is inside of the campaigns folder when it needed to just be inside of the campaigns folder. However like others before me, it only generated some snow trees and no other normal trees thus making it unplayable.
Base: Dirt, Grass, Stone
Additional: Snow, Jungle
Water: 1 Lake, no rivers
Iron & Coal are guarenteed to be on the top level
Wiki states the above, however when I entered the game I had 2 lakes one at the north and one at the south with a river running all the way from north lake just down to the south east side of the south lake but not touching the south lake.
Found coal on the surface but no iron.Edit
: Oh and I did find one lone frogman down at the very south west corner of the south lake, with the only jungle tree he was standing right next to it.
I'm guessing something has changed in the coding between when BVierra posted the map generation code back in what? January? and in version 0.47b that is not working correctly so it's just generating a normal map. The 2ND map that I generated was littered with froggies, as well as a huge river running through the map and no coal or iron on the surface.
