If your Twitch account notified you of the Drops being applied to your account, we would like to gather an image of your Inventory. You may find this via the drop down menu on your Twitch account.
TWITCH.TV > ACCOUNT > INVENTORY
Can you please set up a case on our Support Site and upload a fullscreen uncropped screenshot showing your Twitch inventory.
Once you have done this, please let us know your case number here on the forums.
