[ Info ] [ Mansions and Gardens ]
The game seems to treat this as the 9th EP.
With the introduction of the Mansions and Gardens Pack, it is not possible to place modular stairs beside a wall unless you use move_objects on. This is because of the coding introduced in this pack for sliding down the bannister" - clearly, if the stairs are next to a wall, there cannot be a bannister.
