I am not sure if this is the correct topic and the discussion is about the thing that happened to me earlier. But this is my experience. I gambled on lucky bit. I sent 0.25 x2 bets on green, both of them hit x0.4 and in return I got 0.2 HTC.  I got disappointed because I lost a big amount on it. All the transactions even confirmed. After losing the money, I roughly had 1.02,earlier it was 1.32. But two days later when I saw my balance  it was back to 1.32 btc. I was astonished. I even went through the transactions of the address from which I gambled. Only 3 transactions showed up which were not from the gambling day. I even went through the bet browser of lucky bit. When I clicked on the transaction link, bc used to show that transaction was not found.

I am still unsure how this happened even after the transactions gained good number of confirmations.
