I have a sheet with drafting views that I can copy easily from project to blank project, but when I try to copy it into a specific project, it thinks for a second and does nothing - no errors or warnings. I now must manually copy all the drafting views and even they don't always copy over, requiring me to copy the content within the views in a new drafting view. This is a giant waste of time and very frustrating. I would really appreciate any help with this situation. What could possibly be different in this model than the others?
