Targeted = fired since the update

Since the latest update, I've been experiencing a bug: when I aim, it fires a shot, and I can literally fire a single shot every time I click on the crosshair. This means I can't play as a sniper or destroy vehicles because the crosshair fires a shot, This ruins all my duels because I shoot before aiming, so my weapon already experiences recoil. Does anyone else have this problem, or know how to fix it?
