I don't know if this has been mentioned before, but my class refuses to update. All requirements are at 0 and have been for about a week in game time but my class doesn't increase.
edit: Oops, I missed when you answered the question before, sorry. I'll double check everything and look to make sure my prestige is above 0.
another edit: It looks like all my characters have a massive negative prestige for some reason, it could be the real bug at work here
