@tady159 From looking over your post I'm going to guess it may have something to do with whether or not the pack you are buying for Sims 3 has a corresponding Sims 4 pack.
For instance, Sims 4 does have Seasons, Cats & Dogs, plus looking over it quickly I'm wondering if Parenthood is somewhat the equivalent of Parenthood. But... There is no Supernatural, University Life, or Ambitions & Showtime in Sims 4.
I must say that it's an interesting logic, but that's just a coincidence...
After I opened this thread, I was playing the game normally, and casually went into the lighting section to look for some items (I also bought new expansions for my The Sims 4, so there were new items). And then, there were all the Plumbob Lamps, including the latest four ones. So I actually got them, the game just didn't give that notification right when you start it.
@tady159, I'm glad you got your lamps! 🥳 Thanks for updating us! 😇
