This game currently is in Gen 6th V1 movesets and stuff, and High Jump Kick for Lopunny is Gen 6th V2. So if they decides update only Lopunny then other people start questioning why not updating rest of Pokémon movesets. So they would need go trough all Pokémon movesets not only Lopunny.
+1 for updating mons to Gen 6ht V2 or Gen 7th V1 or Gen 7th V2.
PS Eterna Forest should have Buneary, but in doesn't have atm!
