Well, my circle of dots has been completed, but instead of having a Badge, the website tells me I have a notification. When I click on, it says "no new notifications" and there's no way for me to clear that pseudo-notification. My badge still says x0, but when I click on my profile I get told the following:
badges: 0
badges given: 0 of 1
Assuming it didn't disappear mysteriously, I never have received it in the first place. Weird bug or am I being dumb? I demand my badge! :P
