I really like the look of the default non-connecting stairs, but actually never use them because of the pathing issue -- you know, that arm-waving thing when a sim realises they can't go upstairs because someone else is already using the stairs? Well, no more, I say!
These are the same old Base Game staircases, now with less arm-waving. As pictured, more than one sim can use them at the same time, in the same direction. Upstairs, downstairs, with arms up, with arms down!
