I lost the paintings my Sims have created when I had to use that workaround twice. They had been placed on the walls, maybe they wouldn't vanish from inventory. Photographs in wall frames were fine. I also had alchemy elixirs disappear from their display shelf storage space -- the ones on the two actual shelves of the display were not affected. Collected metals, gems and insects didn't vanish from their displays.
I don't currently have a sculptor, inventor or nectar maker, so no idea if any of their creations are affected.
