(Sorry for the copy/paste from another thread here)

Hey everyone! We posted this update on our forums here:

While today's hotfix addressed the duplication issue, you may find some unintended items in your displays and vending machines. We advise you to look at your inventory to ensure the correct items are listed for sale and on display. After you remove these items they will no longer be on display or listed for sale unless you reassign them. Thank you for your patience.
