I have the exact same issue :C :C :C! It's unbelievably frustrating when you're trying to get to a certain amount of followers, but this bug keeps killing the survivers off... yea... Otherwise it's a great game and mp!
it is a gltich in the game apparently some people are getting it worse then others. For me It will happen maybe once a match and my guy will freeze up I can still look around and everything just cant move and it will last for up to 15 seconds sometimes but usually only 5 seconds.
