Hiya! In my forum, we noticed that the badge (here especially “First Onebox”) is given (i.e. a notification is sent) even if the badge isn’t active. This leads to a problem, when the badge isn’t active: the notification link leads into a “not found”, and the badge isn’t listed in the list of badges for that user (that still got the message).
To clarify: Badge notification is sent, even if it’s not active.
