Ask HN: Is this podcast feed malfunctoning or am I going insane?

Here's a podcast I enjoy listening to. https://cakewatch.fireside.fm/ Observe, episode 57 is online and happy. Now follow the RSS link at the top of page, just under the banner. Episode 57 is missing with 56 ("Montagegate") is the top episode. Since my podcast player relies on RSS feeds, I can't play this one. I've reported the issue but I've been told that the RSS has episode 57 as expected. I keep looking at the XML and 57 isn't there. Could someone please confirm what I'm seeing or am I going insane?
