I traded these in another game (which I beat) from Jasmine and Steven.
I made a new game and decided to use their .PKM files to transfer into it...
But they won't pass the legality check.
The IVs and Natures haven't been altered, but I did change the names. Would that be the cause of the problem? I ran it through the TrashBytes.exe, so I assumed it would be fine, but...
(I also put in EVs, but I'm assuming they shouldn't have an effect on the legality of it)
