Gathering wild plants, berries, mushrooms, and herbs lowers the quality of that tile but there is nothing at all that increases the quality of any tiles....
If this remains this way, the entire world will be nothing but a q1 wasteland eventually...
How about when it rains, the quality has a small chance of increasing and the higher the quality the lower the chance?
There really needs to be something IMO...
Also it would be really nice if we could plant grass back on the dirt tiles that we terraform...
And please fix tunnels as soon as possible! And please don't say what's wrong with em?
