The last time I played Factorio, I remember creating large swatches of beautiful green grass with my landfill. Load up the latest .18 to start again and it's this ugly brown dirt packed stuff. How do I get the grass back?
Landfill change is mentioned here https://factorio.com/blog/post/fff-312, it was changed a long time ago, but I dont know in which version. I'm sure there is a mod to change landfill design back.
The grass could also be ugly if it clashed with the terrain it was placed in.
More significant is that landfill absorbs 0 pollution now. It used to absorb the same as grass, which was slightly more or less than water, depending on the patch.
