Edit action performed: assembled video from clips I uploaded, some of which I trimmed, some stabilized, some did nothing, added short transitions between, some I pulled into the editor multiple times to trim down different segments of a long clip. 

Published the project, but the video ended up reporting that "the video you requested is not availble" after maybe a half day.  Worse yet, the project is gone from the editor, so I guess I have to start from scratch?  All that time, just wasted.  I've published many other videos with the editor.
