I do plan on adding some diagnostic options to the settings. One of these would be a tool that goes through the library looking for any songs with missing files and lists them (with an option to delete those songs if desired).  Perhaps I'll add this for the next update to make it easier to determine if this bug is still present.

At the risk of stating the bleeding obvious, that would be a huge help.

One slight concern is, if we determine that a file is missing (after doing a restore) we wouldn't have the file for you to examine as to why it might have gone AWOL in the first place - that's a nice Catch 22 situation.
