MW3 Survival lag

[non ame]

So just wanted to play a lil bit survival with my friend and i experienced a really strange bug. (he lives in the same city as i do)
Because of this bug its almost impossible to play this game mode. (the missions mode is fine somehow ... :/)

In the first 3-4 waves everything is ok, but later on the game gets out of synch. My friend is in a different wave then i am.
It happens very often that i see him get shot but he tells me that he is alright.

Anyone else got this problems?

Thanks in advance

Happens to me aswell, but only when playing mission. Survival is always fine. Really blows when it happens on the end of some hard mission >.>

Survival is bugged like a motherfucker, just go ahead and wait for the patch..
