Achievement "bug" that I was able to resolve on my own

I noticed that I hadn't unlocked the "Thanks, Johann!" achievement for What Remains of Edith Finch according to the tracking on the site. I forced a refresh of the achievements for the game and now it shows I have unlocked it.

I find it rather strange that I had unlocked all achievements for the game on the same date, but the site tracking didn't properly count that one for more than a year, even after the implementation of the ability to force a refresh of your Gamertag.
