I'm new to Motion, my apologies for having to ask the following:
I have been trying to import a shape into the Shapes library, and all of a sudden I have only 25 shapes there. I'm pretty sure there were many, many more there a few minutes ago. When I close and reopen the file, a pop-up tells me that Media is missing, though no names are presented. In the Timeline layers some items are showing with a "?" (e.g. French Swirl). If I isolate it, I see only an empty square with the transparency blocks, indicating the shape is not to be found.
Where could they have gone, and how can I restore them?
