Players lose stamina even when not moving, aiming down sight, or touching anything. When sitting still my character regains his breath, and saturation returns to my screen. 10 seconds later, my character is out of breath for no reason, and the screen becomes less saturated. This cycle never stops. I do have full gear and a full backpack with 2 med kits, 2 ammo boxes, and a case. It is either a glitch, or I am carrying too much.
