Locke to Gogo?

I have hit a complcation. Once I change Locke's ability from steal to something else and leave the menu, steal is no longer in the game untill I get Umaro(since I put it in his empty slot). So when doing Locke's scenerio in Figaro if you've changed his abbilities it's un passable. How do I fix this error?

I don't think it's an error it's simply how the menu behave. Since nobody has steal it doesn't appear. You will have access to the abilities that OTHERS have. I think that you can't remove mimic from Gogo and it was meant for a reason.

Edit: You could hack it to make all the ability appear if there is place in the menu. That would be taken care in bank C3 but I don't know more than this.
