Hmm, last weekend someone posted screen of very hard decission he had to make between Sasuke and another Sasuke. Welp, game decided that you definetely would use some Naruto, embrace it ;P
But seriously it's a bug i think, it doesn't have sense to be given such "choice" :/

your only other choice would be sasuke anyways

Hi there,

Your situation is not a bug, it is just a rather rare occurance :)
Good luck next week, hopefully you will get the choice back ;p
