yeah, it sucks. but i guess it's due to them being linked to your nnid rather than your pnid... they're still there on your nnid ;)

you and me both. there are a couple threads on the pretendo support discord talking about it, and so far the only fix requires a backup of your SD card from before the badges disappeared

I dont think theyre on my nnid either. I didnt back them up.

joy emoji even

Heyy, Wii U sjc here to say that my badges were in fact backed up on my laptop and they have returned to my home screen :)
