Moving out a household and lost there furniture

I have tried to move my current family to a new lot i pressed to keep furniture but it not in the household  inventory after moving i tried doing this from the phone and the computer. it the same outcome both time i even tried to restart the game and try again and it still did keep the furniture. my family live in San Sequoia and I want them to move to Innisgreen. as I built them a house and everything I tried moving them to an empty lot but that didn't work. I am not using any mods in my game I do have mods but I moved them out of the sims folder as I know it can sometimes conflict with the moving process I dont use cc in my game.
