I've only just noticed this, but I've had 1,244 achievements for weeks and I'm at 1,241 on the HS table. I also just gained a bunch more and it's not budging at all. I assume it's just still for everybody, but I miss this feature. :/

I just took a look at the the High Score Table and it's listing you as having 1284 achievements now. :)

I'm going to go ahead and lock this up as having been resolved.
