[XB/PS] Unable to Save, Error Code: 34 & 21

I play on Xbox. My TWO YEAR multi generational Sims family is GONE. I saved the main siblings in my gallery and attempted to play 3 times. Each time I have loaded them back into a new game and started playing, I can’t save anymore. I’m getting Error code 34 and the file consistently deletes. This last time I only loaded 2 of the families into their homes and the whole file wouldn’t save. So I let my daughter play her saved family and that was only one family - same thing. Error code 34 and the file was deleted. I didn’t spend over $2k on every expansion pack and kit to not be able to play. I own everything and I’m angry.
