There's no "inventory glitches". Containers are closed in your inventory. If you actually looked at the controls on the bottom of the screen you'll notice the "Open/Close Container" button (R3), and if you looked a little closer at your worn items in the "Equipment" section, you would be able to tell the difference between what items are closed are what are open. Not a game developer issue, more of a "you're a lazy retard" issue
