I added twitter, youtube, del.icio.us and facebook accounts a few minutes ago, but now del.icio.us and youtube are gone from my "using" and "available" lists of services. Is this a bug? I was getting data retrieval errors for del.icio.us at first, but not for youtube. facebook and twitter seem to still be functioning normally.

Tried clicking on the play button for a YouTube video that my friend posted, and it jumped back to the top of the Lifestream. Clicking the video thumbnail does the same thing.
