I deleted my NSMBUD saved game. I immediately restarted the console but it's still gone… I tried to restore it with Nintendo Switch Online but I can't choose anything.
Unfortunately, the data is gone.
Ok… Was almost at Peach
You can do it one more time, I believe in you Champ.
I know the problem
This happened to me 3 days ago! I replayed and got to halfway where I was before. 5 minutes ago it all deleted again. I am flushing the game down the toilet
