Yes, I was aware of this. For the benefit of the other readers, in Dream Card the game will sometimes give the optimal 5th card on the deal based on the first four randomly dealt cards. The probability of getting a Dream Card in Bonus Poker is 46.7%. The player can always reject the suggested Dream Card and switch to any other card still in the deck. However, the advice is always correct, as far as I know, except in this situation with Bonus Poker.
If the player gets the Dream Card, then the probability the other four cards will fall into this situation is 1.49%. Given the 46.7% probability of the Dream Card, this situation will happen with probability 0.70% or once every 144 hands.
Using my video poker hand analyzer, the expected value of a pair of fours in 8/5 Bonus Poker is 0.855134. The expected value of a pair of 5's to 10's is 0.813506. So the cost of the bug every time it occurs, assuming the player accepts the Dream Card, is 0.041628 in expected value.
The overall cost to the return of the game is 0.006955 × 0.041628 = 0.000290, or about 0.03%.
