Hearthlings should store wood and stones in piles without having to “build” them.
It might even be better to treat piles as chests/crates so that the items doesn’t get unusable.
it would be great if I could place designated stockpiles next to a new build site and the Hearthlings would use that.
Right now they don’t take wood or stone from piles and if I select “harvest” from them they will start moving the wood to free spaces in stockpiles instead of prioritizing it for the builds.
