Well, I've figured out how CoinPot is funding the Challenges program... Four different times today I've gotten error messages when claiming from CoinPot/Moon faucets... twice from Bonus Btc and once each from moonlite and moondoge.  Each time, my timer reset to zero but I didn't get credited my coins.  Add this to the fact that I'm still not getting Challenge credit for all my claims, and I think I'd rather just roll back the site by a month!
