Rooms are empty

I was really big into this game back in 2020/2021 but my computer went bad so I had to stop playing. I didn’t get another laptop until recently (I had been using my wife’s Chromebook for anything I needed) and downloaded the game to play again only to find all but two of my rooms completely empty, there is only wallpapers and flooring in each room I found this to be incredibly odd and wanted to share. Has this happened to anyone else perhaps?
