I downloaded the Smartmap map script, I think it's really great and makes perfect land for the type of games I want to play, but it has one problem. Players that start in the middle of tundra /desert / jungle do not get their lands "normalized", as in, surrounded by trees, with bad tiles replaced by plains and jungle removed. This might seem unnatural, but this is completely preventing me from using this script effectively.

I was wondering, is there something I could add to the script or an option I overlooked to add this feature that most other map scripts have? Any help would be great.

I had this problem too. Unfortunately we just switched to Full_of_resources instead. Hopefully this will be fixed.
