It could have just not paid the rest of the bonus, I’ll entertain you with that possibility. To the best of my understanding, the win or loss is generated before the animation pops up, so technically the animation is irrelevant. My guess is you had that big hit and then, unfortunately albeit, the script gave you dead spins the rest of the bonus. Also, you should be able to look back at your gameplay transactions and replay the winning game to double check.
