Added Web Page loses link

I added links to Evernote notebooks to Scrivener by using Add > Web Page… (described here: … ive-links/ ). It works great at first, but if I come back to the project at a later time, the Web Page document is just blank. Any ideas what is happening?

As far as I know that technique makes use of a loophole in the WebArchive format which slips live data through the archived content even though it should just be recording the state of the page at that time, 100% offline. It’s technically a bug, so if you find it works from time to time, feel free to exploit it, but don’t depend upon it—especially if you need to go on the road as it depends on live Internet access.
