I was deleting some old episodes of a podcast I like—just to get them out of the way in the episode queue—and I accidentally deleted an episode I wanted to keep. Problem is, it seems to be gone forever.
Swiping down on the page to refresh the list doesn't make episodes I've deleted reappear, and there's nothing in the show settings I can see that would allow me to re-download deleted episodes. It's effectively as if deleted episodes no longer exist, as far as my phone is concerned. I've force-closed the app and restarted my phone since discovering this, just in case. It made no difference.
Am I missing something obvious? What, if anything, can be done to un-delete deleted podcast episodes in the iOS 6 Podcasts app?
