Close the game when you finish playing

Leaving games open to take a break can cause unexpected behavior or slow down your console, so it's best practice to fully close them when you're done playing.

To close a game on Xbox, press the Xbox button to open the guide, highlight the game, press the Menu button (the one with three lines), and select Quit. 

This will prevent saving incorrect data, such as an empty Inventory, and ensure you do not lose anything when you decide to continue with your campaign.
