When I click on the Most Achievements link in the leaderboard, the highlight at the bottom of the page that shows me my rank says that I'm #191. This would be nice, but it's not correct -- I have 128 achievements, which puts me in 1697th place.
If I navigate through the list to find my correct place, I do show up with my correct rank in the list once I've reached the 1697s (page 171, woo!). If I click back to the first page after doing this, it snaps back to saying that i'm in 191st place.
ETA: This may be the same as a bug already logged! beta.glitch.com/forum/bugs/... Sorry if this one's a dupe.
