Recover unsaved document?

I opened a file from Dropbox and added several pages of content to it. I went to click save and the program froze. Then my computer seemed to crash and when I started it back up, libreoffice ran recovery, but did not recover the file I had been working on. Is there anything I can do to bring it back? I had three hours worth of work in there :frowning:

LibreOffice should offer you to recover your document once you started LibreOffice after crash.

You can check your recovery folder if you go to Tools → Options → LibreOffice → Path. There is location of your backup and temporary files. Just go there to see if anything is there.
