yup, it looks like things go “back to normal” in the timeline after about 1-4 hours of posts, at least according to my forum view, but the software is not behaving consistently. looking into putting up a notice/banner somewhere at the top of the frontpage, so it’s visible in the “latest” view.
edit:
per @emenel’s suggestion, i’ve put a temporary notice at the top of the forum. it’s possible this thread display issue will resolve itself when discourse refreshes its cache.
