During a game - mid switch over/at half-time, if you check someones profile (I'm on xbox) you can do absolutely nothing when you re-enter the game. The screen stays blurry and buttons dont work. Can't even press start button. The Xbox home button works tho.
So the only option you have is to wait until the game ends or dashboard (and get penalised for 5mins)
You will stay like this even during overtime. (I play hardcore ctf)
Like I said, it only occurs if you check a player profile during the break. When the game is in progress it seems to be ok
This happens to me and the guys i play with too! Needs to be patched asap!
