Nintendo has released a version 1.1.1 update for Animal Crossing: New Horizons on March 26, 2020

The update fixes a “serious bug” that affects gameplay, which we have found to be the item duplication glitch. Please keep in mind that you won’t be able to go online until you’ve downloaded the version 1.1.1 update, so if you want to duplicate anything, you should do it as soon as possible.
