Is it yours or traded?

Did you get it through hacks?

if you used a hack or AR, sometimes it will mess up your game -_____-

Answer 1

Well, if it's legit, then it's just your game.

But if it's hacked, or traded from someone who hacked for it, that's your problem.
I highly suggest releasing it, or just starting a new game to fix your problem, if that doesn't work. Then you might want to go game shopping, because it screwed over your game.
