Just so that you know, I just added another layer of supergrids to the map; in other words, the map is 7x7 supergrids now.
There are no minimaps for the new grids yet. They'll be generated incrementally starting in about 10 hours from now. I don't know how long it will take, but it wouldn't surprise me if it takes a day or two; the minimap generator really needs some sweet optimization.
Area-wise, this addition means that the map has about doubled in size.
EDIT: I should mention, too, that wilderness spawns won't happen in the new grids. At least not yet.
