I purchased the Sims 3 expansion packs Roaring Heights, Seasons, and Island Paradise, but can only find Seasons and Island Paradise. I also tried starting the game cause I thought it might just be a new town and automatically add itself, but no.
roaring heights is sims 3 DLC item the code is redemmed in your sims 3 account you once the world is downloaded and installed it will be in the main menu +new game to select the world to play in you will still play from whatever game you normally play from there will be no shortcut icon or launcher icon for the wold and it will not be in your origin my games tab
FAQ store worlds there is a guide in there in how to redeem the codes in your the sims 3 account then download the world from there and install it , if you redeemed the codes in origin first then you may get or have an invalid/used code if that happened to your code you'll need to contact CS
