Many players still don't understand the action points in OFC.  They play with a short stack, and if they hit fantasyland, they have very little action left.  They win much less than they think they are supposed to, and think it's a software glitch.  As a result, these players may stop playing, and that's bad for the games.

Perhaps there could be a pop-up briefly explaining that you can't win more than your starting stack on any given hand, and that fantasyland counts as part of the same hand that qualified for it.   This can show when someone joins a Chinese table, and of course a check box to stop showing the message to those who have seen it.
