My team and I have had instances where fonts would disappear in Adobe Fonts mid project. We would be at the end of a project, ready to finalize, and an InDesign file would show the font disappearing. Not deactivated. But completely gone.

Balboa is the most recent example. The Regular, and Italic variations all just disappeared. We opened a document and get 180 missing font errors on the day it's to go to print. This wreaks havoc on our layouts. Fonts should NEVER completely disappear.
