I know there is an issue with the Sniper in which the game doesn't tell the server you shot a bullet unless the bullet hits something (object/player/vehicle). Therefore, it doesn't realise you need to perform the reloading animation.
The only way I can fix this is by constantly checking the player's Sniper ammo, and if it decreases, apply the animation. I will do that at some point, but it's not high priority.
I'm moving this to invalid because it's been reported before and is a known issue. Please search before posting.
