I show oak the bulbasaur for stone...i went to train it and now that i'm back is not recognize him...i already have charizard an blastoise stone, this time oak said the poke was ok (is more than 91 iv) but when i come back with the same poke full trained it asked again for a squirtle charmander or bulbasaur. I dont wanna do twice the same process, i had to do only the last fight with oak, can u please help me? pretty sure is a bug or something like that
