Strangely, two of my filenames got swapped for the project. I was lucky I looked up a tutorial file which I never saved, but my project's timeline was in there, but pointing to my other project's assets. Scary stuff.
Before I start any project I set up a working folder, and create Folders inside the main folder for "Media", "Images", "Audio" and "EXPORTS". Then I organize all the media within those folders so its easy and quick to find what I need!
