Uh oh, guys... So I switched to a 128 gb card a bit over a week ago, ordered it from NCIX so I'm sure it's legit. Right away I noticed load times weren't fantastic compared to my old 64 gb card, but I figured that was a negligible issue. Tinkering with homepass today and noticed when I came out of the settings app, the OS hanged for a solid minute and when it finally came back it'd reset my theme to the default (though I could change it right back without issue). Downloaded something off the eShop and it took like 2 minutes just to start the download (I assume that's the point where it populates space on the memory card). Just now I was clearing out some streetpasses and I black screened. "An error has occurred", that one. Reset and everything was fine (though it again hanged and forgot my theme). What do, GAF? :'(
