Gaming Miiverse comments not showing up in Super Mario Maker

[MushGuy]

OK, I noticed something weird ever since I migrated my game data to a USB drive. Usually, when I finish a stage in Course World, I get so see Miiverse comments and drawings before I decide to repeat the stage or choose a different stage. However, after the migration, I don't see anymore comments. I tried deactivating the comments, and then reactivating them, but nothing. And that's weird, because other games, like Super Mario 3D World and Splatoon still have the Miiverse comments working. Is there a way to make them work again?

OK, I think I finally solved the problem: I tried deleting my save and starting a new one. The Miiverse comments do appear. I restored my original save with Saviine, and the problem returned, so I tried a different thing. I changed the comments settings to regional, and the comments went back to appearing. So far so good. Then I changed the setting back to worldwide, and the comments in that setting returned, too. Finally, no more worries!
