60 day challenge won't update.

So the title pretty much says it all. Tuesday, day 51, I was at 5 days, 20 minutes. Wednesday, 5 days, 2 hours. Tonight, I was up to 5 days, 4 hours.

Sounds good, right? Yeah, 'cept I'm still on day 51. Bummer.

Any ideas what's going on here? I'm going by the time on the stats page, naturally. Some kind of bug?
