People often edit a map's size, forget to update map_constants.asm, and then reopen the map with the default size selected, which comes from map_constants.asm. Thus the size they open it with is now too large or small, and they get an error. The error should remind them to change the map size in asm.
Alternatively, we could default to a valid size, not the one from asm. But that would be misleading, since people would build their game and wonder why the map looks wrong.
