Apparently P2 has 1 frame advantage when taking a hit compared to P1, P2 recovers from a blow 1 frame earlier than P1, this is a test of a new code added to handle this bug, as you can see both players now take the same amount of frames to recover, but visually you can clearly see that there is a difference in the sprite that is displayed, but it is just a cosmetic difference now.
