Sooo, first off this is to get my Achievement.
lol
But on top of that, some of the achievements seem to be back dating, and some don't.
And others are just sporadic.
For example under Level Up I have acquired the "be a member for X years" achievement for years 4,5, and 7, but not for 1,2,3, and 6.
Is it just taking a while to back trace achievements or is it just awarding them randomly for past acquisitions?

In a Community Event, if you already have the Artifact being rewarded, what do you receive for achieving that level??
