There is a bug in the OFCp Progressive games.
When you are in fantasyland and have the opportunity to play a full house on the bottom and another full house in the middle, you'll be prompted with an error message upon clicking the "Play" button. The error message reads something along the lines of: "Your hand is fouling. Are you sure you want to play this?".
Thought I was going crazy triple and quadruple checking my hand looking for the error (there wasn't one).
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.
No, I think he talks about a real but minor bug in the high variations.
To be more specific, let's say that we are in fantasy land with the possibility of placing two full houses with AAA, KKK, 99 and 22. If we place AAA22 at the bottom and KKK99 in the middle, the "foul detector" reacts and invites us to place AAA99 at the bottom and KKK22 in the middle. It would therefore seem that instead of taking into account only the rank of the trips it does it for the rank of the trips AND for the rank of the pair.
I have already forced this situation to see if the hand actually ends up being invalidated and it is not. So this is just a minor bug.
