I got a superstar that I´ve added attires, I erased the attires in the arc using a hex editor and updated the attires I let him with X-Packer.   Example: I got 10 attires, I erased all the attires and let only one, I updated the arcs adding 3 attires, to fix the values and to correct if I made a mistake erasing more or less values. But the game gets loading forever.
