The below gif shows what happens when I copy these tables. I have discovered that though they disappear for a while, they occasionally reappear again. But it’s unreliable so I usually work with a file until I can succesfuylly copy a piece of furniture again. It’s a difficult one. I tried exporting this space from the project to upload, but the file doesn’t have the issue.
Hi @djhg, can you share that file so we can take a closer look?
It’s here (but I can’t reporduce the issue. It usually crops up after moving things around for a while.)
