Flair not updated
Combined Flair is best thing to put on website, but it isn't updated in real-time. If not updated in real-time, 5-10 minutes would be OK. But, I notice that it is intact for many hours. Please, fix it.
And I doubt it'll be changed anytime soon. I'm not a developer at Stack Exchange, but it will be quite a load of work for the servers to recalculate everybody's flair across every Stack Exchange site once every 5 to 10 minutes. All for no real, conceivable benefit that I can think of.
