Every now and then, when you go to fire the sniper rifle, even if you have ammo, and a full clip, it won't fire. No matter how many times you click the mouse button or reload the gun it won't fire. If you switch to another weapon and then back again, it will fix the problem.
It happens quite frequently, but usually only when you're being shot at by multiple enemies. As a result it's really annoying.
