Linking Origin-Steam account
So....I linked my steam account to origin account to re-download the DLC Packs, then I unlinked it and linked to my own origin account with steam sims 4 base game and it appears that doesn't seem to work at all, and it's just not really fair honestly. Only my saves shows up yes, but DLC packs don't show up in-game at all.
I even followed the Sims 4 Guide "New guide on how to use Origin DLC with the Steam Version of Sims 4" I copied the Origin folder to Steam folder, and it doesn't work at all.
I honestly think it's not fair, because those DLC packs I've spent on and I really wish not to re-purchase all of the DLC packs again.
@fireadore If your Steam account isn't linked to an Origin account that owns the Sims 4 packs you want to play with, you won't be able to use them. That seems entirely fair. Steam needs to know that you own those packs before it will let you play with them. Otherwise, any number of people could go around linking their Steam accounts to one Origin account that owns all Sims 4 packs, then unlinking and letting the next person link the same Origin account.
If your Steam account is linked to the Origin account where you own Sims 4 content, you'll be able to play with that content.
