Currently, rock patches can't be removed so once your village grows enough to meet one, you have to deal with it forever. But how?
You can't place structures on them, so it can't be used as part of village infrastructure.
They can't be paved, so you can't leave them even as some landscape art.
And the only use they have is to get some stones, but you need metal to do so, and that means you have mined ore and definitely can mine stone.
So the only purpose they serve right now - is just to make ppl sad. Not cool.
So please, let us at least build on them (in case they meet flatness requirements). Then we can use them for larp at least.
