I placed a large garden bed on the roof, the floor was made to look like a dirt floor. The deed poofed upon placing but the garden bed didn't appear. and I tried to go into customization thinking it would go into the moving crate, but the gump came up letting me know it was there and then was freaking because I could not see it to even chop it. I was heading downstairs and there it was, the floor below. So I was thinking if you are missing yours, and you placed it on the bottom floor, it may be underneath. I have some randomly placed parrots in my house. When I changed the foundation, they all went under the sign. I was freaking yet again. lol I went into customization once again and they all went back to their perches. These unnecessary heart attacks are for the birds!!!
