Still all weird but it's not hurting anything.
Still getting the little leftover box on some pages, a green "start download" button on the walkthrough page and the site menu on the left. (Was that always there on pages other than the homepage?)
A couple of pages do have the Interact button, like the GB Interviews page. I only saw that because I'm looking for problems. I think it's on another page too.
Anyway, please don't worry about it. I imagine it will be back to normal one of these days soon.
