WTF is this gold square??!?

plowed grassland has a chance to decay into moor

Really? So even if you took the precaution of having a tree to hold off the decay, it might decay because you're farming? If anything, I'd expect plowing to reduce the decay of the dirt. I guess you're agitating seeds of all kinds to start growing. I was really hoping I could keep grass at some point, though. I don't like all the doodads that show up with moor and block straw and fibers and just generally looks like blocky weedy crap.

well, i think pavement will restrict it from going beyond that border, and you can always re-grass periodically if you get a few that turn to moor
