Hi, I just wanted to add that if your work is deleted there is another option to restore some of your project — Your computer will not delete audio files created in an unsaved session! It's tedious, but you can still locate them and piece a project back together.
Control click on project > Show Package Contents > Media > Audio Files
If you have labeled each track like a good tidy engineer, you should be able to find your files, then import, or drag and drop files into Logic.
Of course, automation, track settings, etc. will not be salvageable, but just thought I should add to this thread for those who may worry that all their recordings are lost!
