okay so i just got jushiro from the tavern, an i lvled him up to my lvl so him an my momo are same lvl now, but when i do the exhange all he has 2000 less bp then her, i even took both of them out of formation so they werent getting bonuses from that. Then did the exchange all again an he still has 2000 less bp then her, can someone tell me why?
