Scrivener has a feature to “Update Links to use Target Titles” for document links. I am looking for the function to identify/mark those links that are dead because the original documents have been deleted. I have a highly interlinked document and could not find that function. Any help is welcome.
looks like this is addressed in 3.1.4 
Glad you found it! I think it might have been your forum post that instigated the adjustment, but I forgot to update the thread.
