Getting 404 page for deleted discussions
When a discussion gets deleted the links to it are still available in the profile and stream (including the content of the deleted posts). While it may be nice to retain a copy of one's own posts (as long as they weren't the reason for purging, that is) the links point to non-existent threads. When following it you get redirected to the 404 page... which has no menu or other UI elements at all (e.g. https://www.duolingo.com/comment/5279846 redirect to https://www.duolingo.com/errors/404.html ). I think there should be a friendlier message and the 404 page should retain the UI - it is not an internal server error where it is better to show a minimal working page than to potentially trigger an error again. It's just an URL that is not working anymore for some reason, not an emergency of any kind.
