@DekaeWoobika Try going into the game's program files and deleting the data for Get Together. The default install location is here:
Program Files (x86)\Origin Games\The Sims 4
Inside that Sims 4 folder, delete the EP02 folder (Get Together was the second expansion released). Then open the Delta folder inside the Sims 4 folder and delete EP02 there as well. Clear Origin's cache (again) and repair the game (again). Then download Get Together and see whether its items work now.
Yes, I’ve tried this too, I’m yet to hear of a method I haven’t tried yet sadly.
