OK, doesn't look like the OP has posted the debug. I'm having the same problem that he was having (setting Tundra to 'sparse' and getting a LOT of tundra). Unfortunately, I have no idea how to get a 'map generation debug' to post. Could you (or someone) tell me how to do this, or point me to directions? Also, I don't really understand the help files. (Probably more a problem with me than with the files!) I am getting hardly *any* horses on the map. How do I increase the appearance of specific resources (or even specific categories of resources)? Again, like the OP, I am using RoM.
