I teamed up with Mira in Wayward cave to help with shiny hunting. I had my Sneasel in front, but I didn't get much encounters. Sometimes I would go a few minutes running around and not getting anything. Then, I switched my Empoleon to the front of my party, and encounters came a lot quicker. Is there an explanation for this? Does it have something to do with affection (My Sneasel has like, no affection while Empoleon loves me), am I just unlucky, does Mira hate shiny Sneasels, or is there another reason?
