I got the furnace blueprint, but when I try to place the furnace anywhere, there's a red box instead of a green one. Where do I put it? Inside my house? In my field? At the Blacksmith somewhere? Please help! Thanks in advance!
Just a little bit of additional information: you can place all machines everywhere in the world. You can e.g. put all your furnaces at the entrance of the mines. But you have to respect the pathing of the villagers, because they simply destroy everything that's in their way.
