Why does a podcast get unsubcribed without my asking
I listen to several podcasts, but a couple of them keep getting automatically unsubscribed. Usually, it remains on my iPod, but says "Unsubscribed" so I can resubscribe. Today however, one of them completely disappeared off my iPod and I had to find it, subscribe and figure out what episodes I'd had in my on-the-go list. Why is this happening? And how do I fix it?

P.S. I'm on iOS 8.3. I don't know why the automatic product info doesn't know that.
