Hey guys, is this mod working? I've loaded it with a creative mode mod, setup huge boilers generating pollution but nothing happens.

Just tested and yes, it still works. You need to make more pollution to see the effect.

In the setup I was producing 6k/min in four adjacent chunks and wasn't able to see it. How much more is needed?

Here are the thresholds taken straight from control.lua (pollution per tile, not per chunk):
["grass-1"] = 50,
["grass-2"] = 100,
["grass-3"] = 150,
["grass-4"] = 200,
["dirt-7"] = 250,
["dirt-6"] = 300,
["dirt-5"] = 350,
["dirt-4"] = 400, ["red-desert-0"] = 400,
["dirt-3"] = 450, ["red-desert-1"] = 450,
["dirt-2"] = 500, ["red-desert-2"] = 500, ["dry-dirt"] = 500,
["dirt-1"] = 550, ["red-desert-3"] = 550,
["sand-3"] = 600,
["sand-2"] = 650
Could you send me your savefile and full modlist so I can see what's wrong?

Ok, so here's the modlist I'm using for my regular game:

"base",
"Aircraft",
"all-tiles-stack-1k",
"AutoDeconstruct",
"ChangeMapSettings",
"cheaper_landfill",
"CleanTiles",
"EvoGUI",
"Evolution Reduction",
"Explosive Termites",
"far-reach",
"Fill4Me",
"flib",
"FreeLogic",
"LogisticTrainNetwork",
"OutpostPlanner",
"PlannerCore",
"quickstart",
"RealisticDecorationCleanup",
"robotworld-continued",
"Squeak Through",
"stdlib",
"TerrainDegradation",
"VehicleSnap",
"WaterWell",
"wood-to-landfill",

And the creative-mode-test:

"CreativeMode"
"TerrainDegradation"

Here are the save files:

I have no idea what's wrong. Both of the saves don't work, but if I make a new game it works just fine. Can you try starting a new game? Also for testing use this command: /c game.player.surface.pollute(game.player.position, 1000000000)

It worked - I created a new game with just the Terrain Degradation mod. Then I created another one with all the mods I've been using, and it worked again, so what the hell.
