I fixed this bug. 
To give a little bit more of a context of what happened here:
Last time I worked on this I added some logic that was a little bit more complicated than needed because Simplecast has a bug, and unfortunately this workaround introduced a bug. 
Usually, https://simplecast.com/oembed?url=URL should return a JSON with some information, but for specific links it does not work.
For example,

https://simplecast.com/oembed?url=https://tgd.simplecast.com/episodes/dan-blackman-and-robyn-kanner-the-power-7fe152f4
Response:

Let’s see if it works:
