Sometimes the weapons will go into a nonstop firing mode without needing to press any buttons. It only happens after the weapon has already been fired and it seems to occur more often after a reload (I think). I'm not exactly sure how to force it to reproduce the occurrence, but if you fire the gun a lot and let it reload several times (and combine some zooming in) it seems to automatically happen.
I know it happens with the advanced assault rifle, but I'm pretty sure it happens with others too. - pistol, shotgun and sniper rifle.
Has anyone run into this issue and is there a way to fix it?
