I've looked everywhere to find information on this subject online but it's mostly all about traded mon's and amie. I have a Pokémon, actually it's happened with more than one, that I have caught in-game; I've gotten up to 5 hearts in refresh- suddenly there doing all those cool things they do, getting rid of status conditions, dodging - all that good stuff. But I check back a few days later after not feeding or playing with them or opening up refresh at all, and sure enough it's back to one heart. I'm not sure if the bonus's or the extra exp actually stayed- that's reallly all I care about, but the hearts keep going down. I thought once you had them full, they were there to stay. Does anyone know why this is happening or if they do still keep the benefits once they have gotten to 5. Thanks!
