I had same bug, site said PAİD but I received 3 hours later, in big payment list 1.5 BTC just paid I followed it..
Support said it is not a bug, big payment=manuel confirm.
Man this is not about payout issues, investment and money is missing. So as i said earlier also either this is
SCAM or a BUG, only admin can tell this so its upto you to invest now or wait for admin to clarify on this.
