[FIXED] Perfectionist Sims painting don't go in inventory when scratched for new

Right, so I have a sim with the Painting skill, he's in a room with an easel, and he's got the Inspired mood. Every so often, he'll autonomously go to the easel and paint on it, as expected. However, sometimes he'll paint on it while there's a painting still on it, with the result being the painting already on the easel is overwritten; it doesn't show up in his inventory, in the build/buy mode inventory, and he doesn't gain any money, so it's not simply being sold; it just vanishes. What I would expect to happen is for the Sim to not be able to autonomously paint on an easel when something is on it, or for the painting on it to at least get sold beforehand. I have also tested this on a fresh save, with no CC/Mods, and the issue still exists.
