Is there an issue with the Round Shares Accepted (Adj) and Round Shares Rejected (Adj) in the workers page?
The only worker that has a nonzero value for those is the first one (youraccount.1). I set up 2 other workers, and while they showed a proper hashrate estimate, the Round Shares columns stayed at zero after leaving 1 mining for a day and another for 8 hours. Anyway, I'm moving my miners back to the first worker until that issue gets cleared up.
