RARE Tomodachi Collection save corrupted screen?

[TheSegaKid]

So I was trying to find odd things with tomodachi collection when I got a screen on boot up with nothing but question Mark's and jumbled words, and when I clicked ok it had a loading circle on the top screen and another jumbled message popped up and when I clicked ok on that, it gave a please set the date and time thing. So I was wondering if this is a Rare thing to happen with this game, please let me know and thanks!

UPDATE! I figured out that the MicroSD In my Acekard2i was dusty, so I cleaned it. When i booted up tomodachi collection, I got the corruption screen but now it's in English! (Please let me know if this is still rare)

I do not think it is rare. There are multiple people discussing this problem if you google. From what i gather, when it happens it can either corrupt entire save and cause 100% loss OR it can reset to your last good save and you still can continue. If you value your save position you should use Checkpoint to backup your save. Also there is a Tomodachi save editor that can help fix saves but i know little about this.
