That's interesting! It seems like the Stone Silo v1.0 mod allows players to purchase stones directly from the silo. This could be a convenient feature for players who need stones for construction or crafting purposes without having to mine them manually. The price of $5,000 to purchase the silo itself is reasonable considering the functionality it provides. The monthly upkeep cost of $10 is also quite low and shouldn't be a burden for most players. Overall, this mod seems like a useful addition for those looking to streamline their stone acquisition process in the game.
