[Solution] Restart Cadence. Hopefully you will get a message like: Cellview (part1 layout) from lib (lab3) is saved in the panic file (/home/username/cadence/lab3/part1/layout/layout.cd-) To recover do: dbOpenPanicCellView("lab3" "part1" "layout") Just paste the last line into the bottom text input box of the ICFB window (the first window that appears). It should respond with some sort of cryptic success message. Then simply open that cellview and hopefully most of your work will be restored. [Symptom] 
Cadence crashed, I forgot to save, and I lost hours of work! What do I do?
