New Mail Duplication Glitch?
Duplicate Items In The Mail
Send mail to an existing resident on your island
A new variety of duplication glitch seemed to have been discovered by players last week. This method involves sending mail to another character on your island and logging out.
Requires Multiple Characters On Your Island
This method will require you to create multiple profiles (and therefore residents) on your island. You'll basically send items in the mail to your character, shut the game down, and the item will duplicate. We do not recommend or endorse using this method, but if you really want to try out, there are videos available on Youtube.
