Yeah, but what was silly of them was to put in "return" tiles at town entrances. Agart is a good example of this: three return tiles at the entrance, when walking one tile further would trigger a return anyway. The grass return tiles really are a waste of tile.
Though the town tileset has several entirely unused tiles, I believe.
... Or maybe that's the town interior tileset. Sorry, This is all from memory - I'm at work right now so can't check my answers.
