Dungeon floors with green walls?

[DK_Kroo]

Hello there not sure if this belongs in CYC but here goes.

I remember that on D:1-15 you sometimes got floor with an alternate layout with all tiles and walls being jade (?) green. Not those spell-reflecting walls, just purely cosmetic. I haven't seen those in ages.

What happened to those? So they still exist? It would be nice to have more layouts like this; the main dungeon gets pretty dull after a while.

I think those only appear if the layout is tagged to use cave tiles, and then only rarely. I was able to get a level to generate that way in current trunk by messing with weights, so it's definitely still possible.
