@mosespippy: I've noticed some leaderboard weirdness as well. I can't scroll past the second page of friends and I can't go back to the first page after going to the second. I've also has a few times where my score would disappear for a while and then show up again later. I haven't noticed anyone at the top of the list disappearing and you shouldn't be able to lower your daily average. I've got 5 total on my list now with an average over 100k.
