We are unable to retrieve timestamp information for this game - all achievements will show as unlocked offlineJust noticed this highlighted on the game page information. Of the 49 achievements I have so far unlocked, all have timestamps, are included in my streak, including my most recent which was just yesterday.
Not sure if this is how you go about it but I think this information should be removed. I hope this wasn't added to easily justify the recent increase of game-save completions
