Vocal doesn't handle the error of a playable media file not being found in the RSS feed

When I attempt to play the as-of-now newest episode of Boss-Level Podcast, it refuses to play for seemingly no reason. For posterity, here's a sharable link to the episode

Investigating I found that "episode" does not have any (individual) associated media, so it would be nice for Vocal to not list it, indicate it's not a playable episode, or open the artical in a web browser.

There's several ways to fix it, but it's confusing when it attempts to play what comes across as a zero length audio file.
