The walls keep on disappearing on me!!!! I struggled to get the floor to fill in and when I finally did, the walls weren't visible from the outside. So, I thickened the walls. But after I tried adding the stone material, all but one wall disappeared again!!!!! The walls are "still there" as you can see on the right, but it doesn't show up in roam, which means it won't be there in the render either. I need the room to be round because I'm making Rapunzel's tower (among some other Disney projects) and it has to be a round room!!!!!!!!!!!!!! Please fix this in your next update or as soon as possible. Thank you
