Map GROUP value not saving on map switch

When the map GROUP value is changed (in this situation, to alter the roof tile appearance in a town) from within Map Properties, you click 'save' but it reverts to the old GROUP value upon returning to the map. A different value such as MUSIC does save on exit and does not revert when returning to the map.

yeah. i should probably grey it out so you can't edit it, since it doesn't save this way. changing the group would also mean some reordering the same way adding a map does it, which it doesn't do yet

But changing the group also makes the design of the roofs change, how can this be done alternatively then?

That's a good point - goldenrod and azelea town share the same tileset, but the roof graphics are completely different. I wonder how it is coded to do that, do you know yenatch?

you can change the group for real by moving the map into the right group in constants/map_constants.asm and maps/map_headers.asm. i think it's just those two files.
