Another thing to try; right after it happens, go to File- Open Backup

Most users don't remember that RB saves a backup of the current version when you save the file. So you may have a few good versions sitting on your system.

Kinda like Source Control for audio.
When you Save you are committing your changes as the current version, and RB appears to just save the song over the previous version.
In reality on most systems it makes a backup of the original, then saves the new version.

Can be a good tip to keep in mind to save work you think you lost.

I suspect there is something in your workflow that is causing this .. could even be a rogue plugin or some choice (like the Delete as opposed to Cut example).
