It sounds like you were playing OFC 2-7, where the middle row is the best low hand, and anything over a 10 low is a foul. Thus a fullhouse would be a foul in the middle. Check your hand history to see if this was the case.
There is no option to store/save OFC hand histories. Can you please fix this. There should be the ability to have all hand histories downloadable or stored locally on a player's computer.
Thank you for your suggestion, we will work on making that a reality.
