this is probably the case of chapter pending approval from new users who tried uploading some. It doesn't appear in your follows unless you turn on "show unavailable chapters", the issue is the home page doesn't update itself for deleted chapters and unavailable chapters that quickly.
@LordPendragon that chapter was the first upload by that user, so that's why it was unavailable from the homepage (unless it's still unavailable (it's there for me)), also, depending on your browser app, there should be something to refresh page (chrome is top right on the three dots then the refresh symbol (arrow in a circle)), either way, this is just the homepage being unreliable
