Hello!

There is no glitch or bug with Wheel of Fortune Event. Everyone has a chance of getting the Jackpot Ninja and having multiple players getting it in a server doesn't mean that the event was bugged or glitched. You chose to piece Minato Namikaze [Edo Tensei] slowly by buying his frags and that is fine, while other people chose to try their luck and got what they want, but there are also who chose to try their luck and didn't get anything, you might've been one of them if you chose to try RNG also.

Additional note, I removed the images you've uploaded. Please be reminded that it is disrespectful to post someone's info without their proper consent. Hope you understand. Thank you.
