Here is how i lost all my project contents.
- Decided to rename the project.
- Used "Save project as..." to the new project name.
- Selected the old project and sent it to the Trash.
- Opened the new project to find it empty!
- Restored the old project from the Trash which was also empty!
- Logged out and back in again - both projects still empty.
- Now unable to reproduce with another new project.
The lesson i have learned is not to trust the cloud, always backup your projects.
