I remember someone saying this: The way your abilities were (e.g. Espeon with Magic Bounce) in episode 10, was wrong... In another words, your Espeon was supposed to have Synchronize since the start, but only now the game is reading the ability in a "correct way"...
Since i don't remember exactly, it might be the other way around (The ability was right in 10, but it's wrong in 10.6)... Sorry, i don't know exactly...
Amethyst please, answer...
