Creative Cloud Library Assets Disappearing

I have been using CC Libraries for years, both for client and personal use. At times, I would think things were missing, but chalked it up to being forgetful. Today, while adding files from Illustrator and Photoshop, and organizing files directly in the Creative Cloud Desktop application, several items randomly disappeared. These assets do NOT show in deleted files either. They do not appear in assets.adobe.com. It's as if they never existed. As you close out more features of your cloud storage, like synced files, I am very hesitant to trust what features are left. I cannot share a library with a client never knowing if the assets I created for them will disappear.
