For some of you I don't think it's a bug, I think you're experiencing the new anti alt f4 that has been put in place. If you get shot at all now you instantly go into shock (not the kind where painkillers fix it, the kind with the icon on the right of your screen). If you logout while in shock, the next time you log in you will be unconscious and possibly bleeding. This is supposed to be a deterrent to people who alt f4 during pvp.
