I just exchanged Wii Codes with my friend. We both made sure that we turned Mingle on for every single Mii and turned Travel settings on. But when we check out the Mii Parade, we see only several Miis from each other's console. even though we both have like 30. Does it take a while for them all to appear? Do they just randomly come in and out? Does that mean that I won't be able to see them all at once?
