Hello QueenSaraphine
The EA app now shows The Sims 4 game tile as Standard Version, but if you previously owned the Limited Edition or Deluxe Version, you'll still have access to all the extra content on your account.
In the EA app, please open your game library and click The Sims 4 game tile and go to Manage Game-> Manage Add-ons. Your extra limited/deluxe edition content should be listed here, you'll want to check for Life of the Party and Up All Night. If you're not seeing the extra content listed there in the app, be sure to let me know!
