Missing Achievement

I unlocked the achievement titled "The Land Down Under" in Gems of War on 12-11-2018 at 11:50 PM according to the site. I also unlocked the "Colonel Muster'd" achievement about the same time on the same day, but it hasn't shown up on the site as being unlocked, though the number of achievements the site says I have unlocked for the game matches the number that my Xbox Live profile says I have unlocked for the game.

This might be only premium members, but to fix that you need to go to that game's page, look on the right side and click the "sync this game" link. Other than that, you will need to get another achievement in that game to force that game to sync.

Status changed to 'Resolved' - Thanks for letting me know. I have forced a resync of your profile for that Gems of War and it's now marked as unlocked.
