I play at AP, and I've noticed that when I play in the HORSE ring games there, the order of the action is actually incorrect sometimes. It seems to happen in the stud hi-lo portion of the game when two players have an Ace showing. In that instance, the player with the worse ace gets the first action (in the example below, it's the A-2 instead of the A-Q on fourth street).
I sent a message to customer support, and they thanked me by putting $10 in my account for reporting the error. I sent another e-mail when it happened again, and they offered me a free $1,000 freeroll entry (normally you have to qualify). That's all well and good, but I think it's pretty important to fix the error ... and they haven't told me that it has been fixed yet. I haven't noticed any other instances, but that doesn't mean it hasn't happened.
Yes, this issue is a lot less serious (no pun intended) than awarding a pot to the wrong person, but it still brings up issues of integrity, and just a few weeks after the 60 Minutes report ... can't be too good for business.
