So I'm making this map that takes-place underground (by which I mean in a winery-interior that's been scaled-up to many times it's original size), and I started making it by using the Desert Town map.
It turned-out I had less room that I needed; so I went to campaign, did terrain generation, then replaced the .txt terrain seed for Desert Town with that. The terrain I generated btw was completely flat and just above water-level, since I thought it'd be easiest to work with.
It works, and I'm able to change the terrain into something resembling what I had before
But for some reason there's a rectangular section of terrain in my map that I can't permanently change.
I paint it, texture it, and elevate it; but when I exit and map and open it up again (even without closing the game) it goes back to it's original state of being flat and grassy.
This is my second time making a map, so I'm sorry if this is a dumb question
I'd suck whoever's **** be grateful for any sort of advice.
