corrupts data when saving mii profile even when nothing is changed

[Pyrageis]

ive tried it on both USA and EUR mode and after hitting save after selecting and mii and even not changing any info at all it doesnt even say the data is corrupt it just acts as if there is no data at all

[Pyrageis]

apparently its only doing it for some miis, no idea whats causing it to happen on those miis

basically the a single mii itself was somehow fucked up, even readding the same mii and then editing that one did same thing even when it was in another slot
