Missing furniture files

[drjerry513]

At least 3 times now, I have downloaded furniture files (Collada zip files) from associated websites and uploaded them to the "Users" category in the SweetHome3D Furniture library using the "Import Furniture" option. Everything seems to go great for days, then when I open the SweetHome3D application again, all my furniture files are missing. As I mentioned, this has occurred at least three times over the past month. I am not talking about a couple of files; I am talking about over 100 files that have disappeared without any adjustments or deletions on my computer. Please, if you can explain what is happening, as this is getting very annoying and frustrating.

On windows/IOS and bought from the store?
If yes then there probably was an (automatic?) update that reinstalled Sweet Home 3D and removed all externally installed furniture and textures. That should have been resolved by now.
If your situation is different let us know.
