Running on latest MBP with Touch Bar, OS High Sierra, CC 2018.
I have lost major projects due to photoshop deleting files when I choose to not save a current version.
1. Open existing project (.psb)
2. Make Changes
3. Decide that I don't want to save my changes
4. Close file - Choose "Don't Save"
After that if I try to open the file from Recent Projects, photoshop says the File Could Not Be Found, when I check the Folder where the original file should reside it is no longer there and the data is gone. Auto Recover folder in Library is empty, Trash is empty.
