After reloading a weapon and attempting to fire, there appears to be no ammo in the gun. It will go through the reloading animation and sounds and the correct amount of ammo is taken from my inventory but when I fire it only clicks. This has happened with a Blaze and an MP5 for myself and with the SKS with a friend. It doesn't happen every time, but completely randomly. Going to attempt to try with other weapons. But so far have only been able to try the Blaze, MP5, and SKS. Will try to update with confirmation from other weapons.
