Sims 4 game crashes when saving and all progress is lost everytime on Xbox one

Sul sul, @BubskibaNation. Let's see if we can track this down to get the game saving for you again.

First, let's try clearing the system cache by power-cycling the Xbox One.

1. While your console is on, press and hold the Xbox button for 5 seconds. Wait for the console to power down.
   
   
2. Unplug the power cord and wait at least 30 seconds.
3. Plug the power cord back in, and press the Xbox button on the console to start the console.

Let's also make sure that your Xbox is updated to the latest version.

Please let me know how that goes.
