I would suggest to stop using Windows. My Linux machine saves the text file in a temporary directory and it will ask me if I want to restore it. Linux also never reboots by itself. It tells you that you should, but never does it itself.

Further, you should not be using your master password.
You should use your posting password for your normal everyday posting.

Your master password should be kept in a safe place. Written down on paper AND saved to a removable thumb drive. Encrypt it and save it to the cloud.
