3 years agoHi @reiiko13,DLC for The Sims 4 is locked to the platform it was purchased on, so owning some DLC on Steam and some on Origin will only allow you to access what you've purchased on that platform.
If you purchased the base game on Steam you can buy DLC for it via Steam or Origin (you'll need to add the Steam version to Origin first via the Add non-Origin Game feature under the Game menu at the top left of Origin).
If you purchased the base game on Origin then you'll need to buy any DLC on Origin as well.
