I don't know about anyone else but at the end of a fight even if I win I can still select no or yes...
They don't show but if you go over where they should be you can still choose them...
Maybe i'm just dreaming but...

i think it's because you are still able to choose if you want to fight again if your losing opponent wants to fight again . if he does and you dont you can choose no.but i have the same problem :whether i win or lose at the countdown screen most of the time the 2 selection boxes to play again or quit are not there however i can go to where the boxes are supposed to be and my cursor switches to the finger and i can select one or the other. it's not a big deal , but yea i'm experiencing it too.
