What's the situation with sha-256 payments? I had a test rig pointed at sha-256 pool for few days , it was probably over a month ago, majority of that time pool was mining BTC. My mined shares appeared as "Estimated Coins" on dashboard, that figure is continuously shrinking by the day to smaller and smaller sum, but it has never moved to "SHA-256 Balances" section and never translated to any payout?
