I noticed some older posts were inaccessible after the redesign, for example going to https://www.hylo.com/post/73129 (from a year ago) seems to just put me in whatever last group I viewed but the post is still technically there, just with the 'all' added to the URL ( https://www.hylo.com/all/post/73129 ). Perhaps legacy post URLs can have redirects to the current URL format?
