I have to believe they are reviewing something other than just the stats and if the player’s started or not, because like many have said, those can be verified in a matter of minutes.
So at this point, my only guess would be account related or the timing / placement of the wager. Now, I have no idea what those could potentially be, but the actual results are indisputable and verifiable in minutes.
My guess is also that this will be resolved via PM and no update / statement will be posted here as is common practice on issues like this.
