Is there something wrong with the BTC pool?  I'm running the SHA-256 Multipool, and whenever it switches over to ZET or TRC I mine and payouts work just fine, but when it switches over to BTC I register a hash rate but I've apparently earned nothing, and I mean like balance is all zeroes even to the billionth of a bitcoin nothing.

EDIT: Also I never get a 1 minute hashrate for my SHA-256 mine (when its on BTC) but I get a 10 minute hashrate.
