I’m playing on an Xbox one and every time I quit out and then jump back in to continue, I lose all my ammo in my equipped gun. It has happened with my submachine gun and assault rifle. Both of which I was holding when I quit out of the game. I will test it more tomorrow but it seems to only happen to the gun I am currently holding when I quit the game. This is definitely a huge disappointment especially when you have gathered a plethora of ammo for your favorite gun and then all of it is gone when you come back in.
