I'm sorry, I totally misunderstood what you meant by Catalina (an island I have visited many times in my youth that is 26 miles off the coast of Southern California). I thought you were having issues with Sulani, as a result. So glad others clarified what you meant. You're very steamed and it's easy to get your thoughts all jumbled when writing in such a state.
I feel your pain. When something like this happens, blows up in your face, it can take the joy you've always experienced playing this silly game, right out of your memory. It becomes a tangled wad of barbed-wire and frustration.
Did you make a backup of your game, prior to the patch? If not, do make it a practice. That can solve many of your woes. I'm very thankful that @Bonxie over at the MCCC mod help thread reminded all of us to do so. Also, making a copy of your saves and Tray folders is wise, too. Your games reside in the saves folder, your Sims and builds in the Tray. Many a time a copied saves folder has rescued my Sim.
Hope you can get your current issue solved.
