We were playing in a fairly laggy game last night and a weird thing happened when trying to aim at a certain member of their team.
He was sniper perched on a railing, not cloaked. I aimed my M4 at him and the cross-hair was pushed down to the ground like a magnet. I thought "err that was weird" and strafed through the door to try again and the cross hair was pushed all over the place away from him so I couldn't shoot him. He then sniped me.
I don't know if it was just a weird glitch or lag, or whether he was cheating. But I've never seen anything like that before in any game.
Facism mentioned something like that happening to him a while a go and it happened to me last night.
The weird thing was that the rest of the game the guy was an engineer and my shotgun wasn't affected by it. Only happened to the M4 but then I didn't try any other weapons. WEIRD.
