Crystal Creations Kit_Bug from the gemology worktable

Product: The Sims 4
Platform: PC
Which language are you playing the game in? French
How often does the bug occur? Permanently since the addition of this Crystal Creations Kit at the game.
What is your current game version number? After two repairs of the game, 1.104.58.1030
What expansions, game packs, and stuff packs do you have installed? All content for this game.
Steps: How can we find the bug ourselves? Make this Crystal Creations Kit content playable, the gemology worktable is not functional.
What happens when the bug occurs? Nothing happens, no error is displayed, it's just this gemology work table which is non-functional, she is buggy, and as a result the whole of this Crystal Creations Kit is unplayable.
What do you expect to see? I want everything in this Crystal Creations Kit to be playable. If the gemology work table is not functional, we cannot play with this kit.
Have you installed any customization with the game, e.g. Custom Content or Mods? After forgetting the very first time when launching the game after adding the kit, I noticed a problem, the gemology work table refused to be functional. So I left the game without saving my game, then I removed all the files from the Mods folder as well as the localthumbcache.package file, and performed a repair of the game.
Did this issue appear after a specific patch or change you made to your system? This problem exists as soon as Crystal Creations Kit is added to the game. Without a mod, whether on an already saved game or on a completely new game created, the gemology worktable remains unplayable, she is buggy. Before making this observation on this gemology worktable, I received the game update, and after adding the kit I applied the latest EA patch released and available wednesday to thursday morning. And the gemology worktable continues to remain buggy, and therefore all the gameplay of this kit cannot be played.

How many of us have a Crystal Creations kit that we can’t play with?

Feel free to describe what happens to you when you try to achieve something on this gemology worktable. As long as she is not functional this worktable, all the contents of this kit will be unplayable, no jewels created and no gameplay in connection with these jewels, only construction mode is possible.

This Crystal Creation content is not working for me, the game does not detect any crystals, metals or models. The Gemology skill and Crystal Craftswoman aspiration cannot be carried out, as is also all the gameplay with jewelry creation and jewelry that has the ability to change Sims' moods or relationships.

- After clicking on the gemology worktable to select a task (Create a jewel, Cut a gemstone), the windows displaying the different choices (Model, Metal, Crystal) to create a jewel or cut a gemstone appear completely empty once the selections have made, there are no Models, Metals or Crystals detected by the game in the Sim's inventory or in the gemmology worktable reserve.

- As for creating a random jewels, my Sim walks up to the worktable and stands there doing nothing.

- If I click Open on the "Humphrey S.A. All-In-One Gemology worktable Items", the window also appears empty, because Metals and Crystals are not detected by the game, neither in the gemmology worktable, nor in the Sim's inventory. In addition, these Metals and Crystals disappear a few minutes after being added to the gemmology worktable reserve.

I also noticed that the game did not save these 3 new crystals and 3 new metals in the collections window once the Sim had acquired them.

As for the steps I took to try to resolve this issue, I first deleted the contents of my Mods folder as well as the localthumbcache.package file and repaired the game. Then I launched the game and my game part (without any mod). Nothing has changed, this kit remains unplayable.

I then quit the game and repaired it again. And once restarted, I created a whole new game part with a whole new Sim (still without any mods in game). This kit is still unplayable despite a newly created game part.

I downloaded the last EA patch released and available wednesday to thursday morning, then restarted my computer. But even if the patch is installed, nothing changes, the problem persists.
