Countertop wizard. Editing countertop shape affects ceiling and floor render. See attached renderings.
I repeated it, to see if it would happen again, and it did. Placing the top via wizard is fine, but when I edit to get the overhang, the floor and ceiling seem to mimic the shape of the top.
I also tried creating a rectangular top and dragging it into place. When I dragged the top into position, the ceiling and floor glitched again.
Dunno if it’s related, but this is an unusually large top (163 x 39″)
