@Challengers I got a little too update-happy earlier today in bringing the Discourse software underneath the forum up to date, and that may have broken the Challenge leaderboard. I’ve pinged @steve-desmond, and I’m sure he’ll take a look as soon as he can. In the meantime, sit tight.
Discourse is doing a lot of post-upgrade processing that caused some thrashing—Steve restarted the Challenge app, and it seems to be working fine again.
