Sims 4 Household Completely Gone

I found I was able to recover it by reverting to an earlier save I had made on the save file, instead of the last save I made before they disappeared. It set me back an in game day’s worth of progress but I recovered. However, when I had gotten off the game and then later went back on, the household was once again completely gone. I’d hate to think I’ll have to keep jumping back in time, basically losing bits of progress each time, every time I want to play. If there’s no solution, I’ll probably try and request a refund because that’s a dealbreaker for me if I can’t actually progress in the game
