Server issues doesent let connect Shots. I also Experienced this yesterday, i shoot a 60! Bullets magazine on a Bambi with an Axe in a Building and no Single Bullet connected to the Server and then he Killed me with his Axe.
Here is one Clip with the Bug:
the Bug is especially in Buildings, on Top, Rooms, Floors. Experienced this so many times, one time a Player shoot a entire Mag on me and i have no Damage, ruined Clothes, nothing! Even in a Building. Halls, Houses, Rooftops.
