I am experiencing the same issue.
I cannot buy skill books from the computer/bookcase, and I cannot buy upgrade parts for object upgrades. The game does not show or recognize these items correctly. I also have an issue with fairy pollen: the game says there is not enough pollen even when my fairy has plenty of it, so the game is not detecting the resource.
I have no mods or custom content installed. I deleted my old saves, tested with a completely new save, removed my Sims 4 folder, repaired the game, and finally reinstalled The Sims 4 with all 54 of my officially purchased expansions, game packs, and stuff packs through EA App. The problem is still there.
I am playing on Mac through EA App. My game version is 1.125.59.1230.
The issue started after the July 9, 2026 update. It happens in new saves as well, so it is not related to a specific household or save file.
The affected features are:
- Skill books cannot be purchased.
- Upgrade parts cannot be purchased/recognized.
- Fairy pollen is not recognized by the game.
Please investigate this issue, because several important gameplay systems are currently unusable.
