Here is one strange glitch which I never heard of before, and you probably didn't either.

So I was playing TIA on Wall Street yesterday, where the glitch happened.

It happened on the second floor of the "spear" building. I was chasing 2 guys with a teammate when I got stuck near the crash pod site. I could look around, I could crouch, but I couldn't move or jump. I also could shoot and melee, but didn't seem to have any effect on the enemies, which appeared to warp a lot.

Then I got killed, and when I spawned, I still couldn't move, but instead of being in the normal first person view, I was in a third person view, not the usual one where the camera is behind the body, but the camera was inside of the character's head. I could see my body when moving the view around, the gun was further away from me compared to the usual first person view, and iron sighting just zoomed in a bit and removed the reticle. The zoom was much like the zoom you get with ripped off HMG's and laser sights in single player.

I spent the rest of the round in a underground entrance, pressed print screen (didn't have FRAPS on) and hoped that it would fix itself in the next round, but instead of ending the round, the entire PC froze and I had to do a manual restart, so no screenshots

Yeah, had the same prob yesterday at a gamed.de server ... all the same you wrote ... I killed me some times with a granade, but nothing changed!
As I was sick of this, I tried to leave the server to rejoine, and than I had the total crash as well -> only with task manager I was able to leave the game
