http://elc.scryptmining.com/ which was the one I was mining on with about 5500 KH/s there are over 220,000 shares on this current round, which is crazy for a difficulty at just over 1. And it still shows that I have 9000 unpaid shares, which leads me to believe that the shares are being reported but the blocks aren't actually being found. I mean, I guess I could be wrong and it's just a stats problem, but it all seems pretty strange.
its a bug with the pool software. welcome to experimental software. (BTC is experimental too, there's no refunds available from the issuing company you bought the software box from.)

i didnt write the pool software and it seems we've uncovered an issue. im sure sufficient logs are available to split out the values properly, i mean i see zero pool giving me proper shares too.
those shares just have to be triggered to be paid out.
at 19400 i have a feeling things will all go back to normal. I think the retargetting interval change confused the pool payout scheduler.
Makes sense, I guess we shall see when we hit 19400, which at the the hashrate it's going at now, shouldn't be too long.
