Steps: How can we find the bug ourselves? Delete the ceiling off a basement. Put a glass roof over it, build the roof from the ground floor. Et voilá, the basement turns into a void. Mine was placed on the big lot in brindleton bay with a glass dome roof. There is a workaround to this issue, which is to place the glass roof on a higher level and drop the eaves. However, when you do that, sims will simply walk through the roof you put down and the eave cuts through buildings on the ground floor.
What happens when the bug occurs? The walls and floor of the basement level disappears.
What do you expect to see? The walls and floors of basements under glass roofs should be visible when a glass roof is placed on the ground floor.
Have you installed any customization with the game, e.g. Custom Content or Mods? Not now. I've removed them.
