You have to "copy" the grass or dirt tile from the palette, then paint it on the ground. If you paint the ground with anything other than this tile (such as grabbing grass from elsewhere on the map, after randomizing everything) it will just paint that tile over and over and it will never randomize.
This is probably something I should fix, come to think of it.
