Household gone

I spent a really long time creating my sims. Once I finished making them, I picked a world and wanted to add them into a lot. I did the FreeRealEstate On cheat and once I picked a house I confirmed. It showed me the loading screen but instead of putting me into the house where they woudl've been, it returned me into the pick world screen. I went back to my chosen one but my sims were nowhere to be found. I saved the game and reloaded it. Once I returned, I could see the newly made sims in the continue/load game preview, but once it loaded in I was once again only showed the world choose menu. My sims are in no houses, and I have no way to find them nor get out of the menu since it immediately goes 'create a household to move in' whenever I click any houses.

I was thinking of just moving my sims over again since I saved them in my gallery. But when I went into my gallery, they weren't there either??

What do I do????
