It has been a year of "fixing"...

I have been trying to fix this For Rent problem since last year and this is my last resort… I've been having this bug in The Sims since the pack came out where I can't build Apartments anywhere outside of Tomarang (It won't even give me the option to change a lot into an apartment lot!), this also includes the base three worlds. I've tried practically every trick in the book,  disabling and reenabling CC,  updating all my CC,  clearing my cache file, And the other cache file for images…  The only thing that I haven't tried yet in fear of losing everything is deleting and redownloading the whole game. But recently, as of today, I kind of figured I should try to delete the For Rent pack itself and redownload it! But when I went into EA and tried to delete it, it won't let me and it says that I have to manage it through Steam but it doesn't even have a Steam icon. Then when I went to Steam to see why it didn't even show up, It shows the pack as if I don't even own it and wants me to pay the full price for it… My issue is that I already paid for it so why is Steam asking me to pay for it again when I linked my EA account to my Steam account? I even have the pre-release items 🙁

At this point, if I lose those three items, I don't even care anymore as long as I can play the thing I paid for! LOL PLEASE HELP
