I’m not sure exactly all of the shows that are missing, but I know that 104, 106-109, the actual 110, not the pre, and 111 are all missing from my iTunes feed..
They are present and accounted for on the server, and in the feed. You need to delete your iTunes subcription, then re-subscribe. Keep in mind, the past shows page not only has every show listed on it, but it pulls from the same feed that iTunes does. If it’s on the past shows page, it’s in the feed.
