Original Rocks and Smoke Alarm Gone forever?

Hi, I recently installed some custom content (CC) for rocks/stones, along with an override to remove the ugly smoke alarm. However, instead of replacing or overlaying the existing rocks and alarm, both items have disappeared from my game.

I removed the CC for both the rocks and the alarm, but my original versions still haven't returned. I have already uninstalled the game, deleted my game files, and reinstalled it through EA, but the issue persists. Even when I try installing different CC for these items, they still don't appear in-game.

I also attempted to locate the relevant game files by navigating to:

• C:\Program Files\EA Games
• C:\Program Files (x86)\EA Games

Google suggested finding the bin file, but I was unable to locate it.

I have the latest version and patches

Packs/Stuff I have.... 
EP01 – Get to Work
EP02 – Get Together
EP03 – City Living
EP05 – Seasons
EP13 – Growing Together
EP15 – For Rent
GP05 – Parenthood
SP06 – Romantic Garden Stuff
SP13 – Laundry Day Stuff
SP15 – Moshino Stuff Pack
SP16 – Tiny Living

I hope this explanation makes sense! Any help would be greatly appreciated.

Cheers
