Lost Achievements (or gained new ones)

[beyondhelp]

I remembered the pride I felt a couple of weeks ago when I broke the halfway mark and had completed 51% of the achievements, but I just finished a game the other day and apparently I only have completed 47%! I can't see any achievements that I've lost but nor can I see any new ones that may have been added. Can anyone shed light on this mystery?

29 new achievements have been added, along with 24 last month, for the upcoming expansion. They don't have names yet, but they exist, and have dragged many totals down. I went from 87% to 64%.

In your personal overview you won't see the new ones yet(despite them already counting for your completion percentage). But if you watch the steam global achievement stats they'll be there (without a real name yet):

Thanks, so new ones have been added; bittersweet but I can now have peace of mind
