We NEED individual railings and option to change ceiling

I think originally during the development of The Sims 4, they thought that adding railings simultaneously on both sides of the stairs was a way to bring more practicality to the game, as that was one of the great initial proposals of The Sims 4 and its Build Mode.

The point is that they didn't think about what kind of problems this could lead to in the future, and that's exactly what we're going through right now.
