Still going after all this time

So Im still pretty happy with the game, but the challenges seem to have been messed up after the Aug. 9 update - Ive completed them all but the badge counter on the challenge icon is saying I have 4 challenges remaining. Also there are minor graphics issues in the character menu that arent really a problem but look sloppy. And I dont get the look of the new coins - what are they anyway?
