I recently refreshed metadata on most of my shows, including Homeland (I don’t have House of Lies), and while everything else worked perfectly, I have the exact same issue with Homeland. I did not change the name of my files or anything else - just refreshed metadata. Similarly, the Plex dance didn’t solve anything, and the permissions aren’t an issue either - I strongly believe there’s something wrong on Plex’s side of things when it comes to the metadata about Homeland. Changing the episode ordering also solved the issue for me, so it’s exactly the same issue with the exact same show, and everything points to PMS working exactly as intended - just no data on the server side of the agent.
