Notification gone missing.

[#1]

When using this URL I see a list of all unread posts. Having read them I used the Options and marked them all as read, on it's completion I noticed that my single notification had disappeared from the Useful links and the Avatar. It may have been undone but I thought I'd check them anyway so clicked my avatar and got this:



As you can see there is evidently something wrong. So I thought I'd mention it here.

It's been reported and reportedly fixed several time @Mook 

Now in the queue behind fixing the Billing system

Well whatever is causing it appears to be getting worse. Get an email telling you you've been 'mentioned' so go to site to see what's being said (I have content off). But on arrival using the aforementioned link and there are no notification counts shown but refresh the page et voila they appear!
