It keeps deleting – Ninja Turtles: Legends Review

I don't know if anyone else is having this problem but, I recently started playing this game again, and I was leveling up, getting new characters and what not, but when I opened it the next day, the ENTIRE game just reset on me, I had to go through tutorials all over again and everything. Today I played it, opened it up, SAME thing happened AGAIN! It would be really appreciated if you could check to see if this is a major bug or something.
