Dank, your bid was probably entered in before the new round started... And thus it went into the previous round's pot and not the current one. So if you didn't get doubled, you should have at least received a partial refund based on the percentage that NothinG states in the rules when a round ends.
That's the problem, I never got a refund.
Partial refund may mean like 0.002 BTC depending on the pot at the time.
Also, did anyone else just get sporadically banned?
