We deal with this by dropping hiking bag on the ground,bag/container on ground to sort items. emptying bag than picking up bag from playing screen.Also if able to, Do not go back into viewingback out of inventory screen while holding the bag or it will glitch again,by using select (inventory button) instead of the B button! drop bag firstThis is more of a nuisance than anything due to the common muscle/mind reflex of using the B button to back out of inventory screens.
