Second, THANK YOU. I've been wondering for a long time if I'm going crazy. I know that every once in awhile, I or another editor will forget to put the URL into an entry, but sometimes I swear that I did put one in and that it disappeared later.
You just PROVED it. The story from which the link is missing HAD the link earlier, and I can prove that to myself because the link is there in the email version. That means that for some reason, Wordpress is occasionally just somehow losing the custom fields from entries, after they've been put in correctly.
So I may still be going crazy, but that's not a sign of it :D
