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

It's been about a month and my reported issues still haven't been resolved, with the exception of connecting to the gallery. I can't build lots/skills/Sims relationships if it all resets to the last save point. It's incredibly frustrating testing everyday if the game will actually save, only to get Error 21 again and again. I sent my game files almost a week ago. I know many other console users are still experiencing this. 
How is it that a single update has managed to disable our games and how is it that the people who don't have mods or anything not provided by EA are the ones experiencing this issue? Please resolve this soon, playing without being unable to save progress just makes the game pointless.
