Hi there!
I'm not sure what's causing you folks those problems. I have the same items from the store plus a couple from the exchange and I didn't have a problem with those due to the update. However, it is true that the update did mess up with some people mods and it might be possible that something in the way you had your content installed made it recognize them as mods (since they are .package files, but I highly doubt so). I'd recommend you try the following:
- Uninstall the content that's causing you problems.
- Run the game without that content (just until you get to the main menu should be fine).
- Download and run Regul Save Cleaner This external program will help you get rid of unnecessary files that might be affecting your game. However, make sure you select the cleaning options that are convenient for you. For example, you might not want to remove your family portraits.
- Reinstall the content that was causing you problems as you would do normally. Run the game again and check if now everything is working as it should.
- If nothing of that works for you, I'd suggest you uninstalling the content once again and re-installing it using CC Magic. Here's a tutorial that will guide you through with this installation.
- If even that doesn't work, I'd suggest you uninstall a re-install the game entirely (which might be tiresome but for the best).
I hope all that helps you find the right solution! Feel free to tell me how that went and in case it hasn't worked, I'll try to come up with another possible fix!
