Thanks for sharing this video. This is an issue that the team has been made aware of. Are you also missing an item from the weekly reset? If so, could you please grab an image or record a short video clip showing that the item is missing in your game as well? If you record a video, please upload that to YouTube and post the link in the thread here.
Please also try these troubleshooting steps to see if they help with the item appearing again. I would also ask that you please make sure you have your latest cloud save uploaded. You can find the steps to do that here.
Please let me know how the troubleshooting goes or if you need further assistance. Thank you!
