Smash Wii U Possible problem regarding challenge

[mysticlink]

I just finished doing one of the challenge.
This special one that take so much of your time.

Complete all-star on hard mode with all characters.
I just did it...but the challenge didn't unlocked.

I wonder if it happenned to other people.

Thoughts?

Make sure you actually cleared it with everyone. I ran into a similar issue on the 3DS version because I had lost and gone on to another character.
Look at your Global Smash Power levels and see if any of them seem kinda low. Or check through your trophies (if you haven't cleared on lower difficulties) and see who you're missing.

Yeah, go through your trophies and make sure you have 2 for each character. Also remember you have to do it with at least one Mii class for completion; the other 2 Mii classes are optional.
