I don’t know if this is a bug notice, a suggestion, or a complaint.
But I just had a goblin camp spawn underground, right next to my ore Stockpile. I mean, one square away. A few game days earlier, one spawned immediately outside the fence to my farm.
They just … suddenly existed. One minute, my workers are dropping down ore. The next second, there’s two goblins, a wolf, and a campfire just sitting there, amongst my supplies.
I feel like maybe there should be a limit as to how close to your area/Hearthlings/constructions that enemies can spawn?
