Only 9 stone plots in a whole region?? Man, that's bad luck! I have 10 plots in one region, and from those 8 are of stone; still haven't placed them producing, DEC requirements are a pain.
Do agree with you on this land importance part - and I was one that thought land wouldn't mean anything to me! Fortunately the team is proving me wrong.
Yep, that is indeed bad luck. I do have a few more in a different region though, but that doesn't help much due to transportation cost.
I produce a lot of wood and iron through, which I sell to buy stone.
Yep, I have same problem; all grain producing plots are in 1 region, the iron and stone on the other; and no wood plots. Already considered swapping 1 stone plot for wood one, but given the difference in materials price it's more worth to keep the stone one and just trade stone for wood.
