Okay, no. I just got smart. I'm copying the link version to the error with embedded videos version. So I'll have both links and comments.
Hmm, it's not just posts with errors that have been duplicated. I just found two posts for the same poem. Odd. Aaargh, and some with embedded link errors that aren't duplicated so I don't know where the originals came from. Grr.
I went looking because I thought I had seen some embedded vids in posts but it was the wrong vid for the post.
Huh, but the correct icon is with the original post. The copy gets the correct icon; the original gets my default icon.
