As I already said before in thread I have same problem, but I tried yesterday to ONLY "log out" from game to the title screen. Then on PS3 I holded the PS button until it comes to the menu to turn off game / controller etc. Choose "Quit game"
from there. I tried it numerous times by now and that works.

You guys on PC could try similar. Choose the "log out" only then just try quit the game however you want. Window mode could just try " red X " in corner or whatever Or try kill it with task manager , ESC etc..

Hope they fix soon though..
