So ever since the update when I navigate to the site after a few hours of inactivity I will not be signed in or signed out, instead it will display the number of XBL friends are online, but not notifications, and the tab where my profile/sign in button should be is blank. If I mouse over the blank sign in/profile tab the usual dropdown menu appears, with "profile, activity, etc." If I click on any of those it takes me to a "user does not exist" page and I will be completely signed out. I'm using Firefox on a Windows, everything is up to date, and I have disabled all Firefox extensions for when I'm on Bnet. I'm going to clear all data/cookies related to Bnet from Firefox, but in the meantime, has anyone else had this bug?
