Actually checking them might do it but just dont run dragonsp.
Because dragon itself only places the land tiles and only edits the map0.mul file, it is actually one of the static mul files that holds the informationm for tress rocks etc.
So just dont run dragonsp or if you map is already created then just run worldforge, the clikc fill\clear at the top of the box it says clear files only have stadix & statics checked, DONNOT check Map0.mul or it WILL ERASE your map. The click go and it will erase all buildings trees, rocks, anything except the basic map tiles!
There ya go, lemme know how it goes...
