I am playing Far Cry 4 on the PS4 and I have been unable to use C4 at all during the entire game. I can select C4 with the left arrow key however I am unable to throw C4 with L2. I have just discovered that if I turn on 'Shoulder Swap' in the controls menu I can use C4 perfectly with L1, however turning off 'Shoulder Swap' causes the exact same issue to arise. Has anyone else experienced the problem or know how to solve this?
