Mangler blank shots

Ok so we all know about the nerf but what’s still annoying is the fact that the mangler sometimes shoots an enemy and it doesn’t register it did it all season 1 and is still an issue in season 2 like how does no one notice this it’s way to common not be noticed. I don’t think it’s desync it’s literally a bug with the mangler that’s overlooked 6 months into the game….
