On PS4, follow these steps: 1. Open Vault 2. Open Character 3. Press the left or right bumper and as the page starts transitioning press the back button (Circle) 4. You will notice the top bar is gone. Pressing the back button (Circle) fades the page but it re-appears. Now the vault inventory is stuck. Pressing the track pad (center rectangle thing on dual shock) will close this no issues, however this keybind is not labeled so if someone does not know of that button to close it, they are stuck in their inventory.
