Update: Now the thumbnails are only half loading and FCPX is crashing every time I zoom in. No project thumbnail in the browser when the project is selected. The original project and another snapshot work just fine.
I need this copy project as all my recent edits were done on it. I can’t even copy and paste the project copy because of the thumbnails not loading and the crashing when zooming to select the entire project.
My machine isn’t the problem. Brand new 6 core with RAM up the whazzoo.
