This mod makes terrain degrade over time by pollution.
Mods introducing new content into the game.
Map generation and terrain modification.
Under some conditions it appears to be possible for the terrain changes to over-write player placed terrain changes like concrete (In the upper mid right you can see a chunk that has become full desert, over-writing the concrete below the boilers): https://steamuserimages-a.akamaihd.net/ugc/775119288858463241/732854865AAEFA6F954569FA2296C22E9E16B3FB/
I havn't probed the bug too deeply, I was just testing out the mod in creative to decide if I wanted it in a long term game.
Thank you for reporting, I'll see what I can do.
Fixed
Could this be an optional behavior? I kind of like the idea of nature trying to reclaim the land right out from under you.
