FAQ
Yes. Strict JSON export preserves all 32×20 terrain cells and placed objects for exact validation and reloading.
The sandbox is exactly 32 columns by 20 rows, or 640 editable cells. It does not claim to reproduce a vanilla farm map.
The board uses 1×1 sprinklers covering 4, 8, or 24 tiles, plus Coop 6×3, Barn 7×4, Shed 7×3, Silo 3×3, Mill 4×2, Stable 4×2, and Fish Pond 5×5 footprints.
An object must stay within the board and cannot overlap another object. Crop coverage counts only crop cells reached by the selected sprinkler patterns.
The sandbox does not enforce vanilla-map terrain restrictions, reserve door or animal-route clearance, calculate economy, or write changes to a Stardew Valley save file.
