Horse Cart and Cargo

Your horse and cart stay in the world: they wait where you get off, follow you or stay on command, and you hitch or mount them by walking up to them. Online, other players see them where you left them.

Horse Cart and Cargo is an entry in the Built-in mods database, listed under On.

Several of these change core rules, so the guide pages describe the game with them on. 'Fixed by the room' means online everyone plays with the mod at its shipped settings, whatever they choose offline.
