For Rent Pack Builds Missing

Hi Sims4 Tech,

I created multiple rental properties, but when I loaded the family that I saved the properties to the builds are no longer available. I still have the family but even their features are different. The spaces I built the properties on are empty. None of the builds I created in different worlds are there anymore. I saved after each build. The rentals were up and running with tenants paying rents and the owner interacting with each. I put in a lot of time. Any thoughts on what happened. 

Thank you in advance for your insight.
