Nothing much, just a lot of tidying up, and replacing some railings around the landing pads. These are a mixture of simple cylinders for the main struts, and a simple repeating texture. It seemed to me that a repeating set of vertical shafts, with no top and bottom, would be perfect for stair cases. Seems to work, though I might need to clean that texture up at the top, with the remnants of a working horizontal bar (it didn't work) still shows.
