Small issue with my last B4 order when BTC was at $492. Sent payment right away and it had 6 confirmations before the hour window was up. But my order expired, I did notice that the BTC is still at the address I sent payment to, usually payment address redirects BTCs to another address (to consolidate payments?). Sent an email to webmaster@bitmaintech.com. I know that BM always corrected such errors, but $120/BTC variance at current price. We will see how do they handle this order.
