was there a Eighth Anniversary Gift Bag achievement?

An achievement for opening a single bag. Pretty sure that's all they had.

You can check existing achievements through the Achievement page, under the 'Personal' drop menu, for future reference of old achievements. I think something like this would be under Items, but unfortunately that page crashes my mobile browser so I can't link you straight to it.

thank you.. i got it under "Items" ... and it was only for opening one
