OK, I got one.

I had been working on a new song and saving it as I went along.

I was in Editable Notation Mode.

Using the mouse, I accidentally placed a note too low on the staff. I did CTRL-Z to undo the note, and I lost almost the entire melody and almost all the chords except for a bit of each toward the very beginning of the song.

Edit, Undo did not bring the missing parts back.

I immediately exited BIAB without saving the song, and reloaded BIAB and reloaded the saved song, which was OK.
