The shooting range is just a piece of unfinished shit. Not only is shooting in this game generally inconvenient and unpleasant, but the weapon constantly jams after a couple of shots. If you press the R button while aiming, the weapon does not fire after reloading. A couple of times I had a reload animation, but the ammo counter did not update.
This update was supposed to come out back in May, but it is now the end of July. What was the condition of the shooting range in May?
