Ended on a hand of: K J A A Q and did not receive the Jacks or Better $1 payout. According to a brief search about the rules of video poker, a pair of aces is considered better than a pair of jacks.
yep, definitely a bug - seems like with when getting a winning of aces after the second deal. interestingly if you get a pair of jacks you get your winnings correctly. guessing aces are low.
