I just wanted to let everyone know that I am aware of the problems that cropped up recently in the Challenges - no split times, and no "new standings" links, to name a couple - though I don't understand how the issues came to be because I didn't touch the code that is now "broken". Nature of the beast, I guess.
Anyway, real life is getting in the way ATM, but I'll get everything sorted out as soon as I can.
Thanks for your patience.
Add: These have been fixed.
