Although seasons all appear OK on the server side, including correct cover images, on the client side show page I get four season boxes: "All", specials, 1, & 2, with season 3 missing. Also, all boxes on the client side show the tvdb image rather than the correct season covers as it does on the server side.
Season 3 episodes are there, named correctly, and show up under "All", and season 3 itself shows OK under the "recently added" page, just not on the show page. That said, is there a way to get the client side show page to reflect what I see on the server side?
Side note, it all looks good from my iPhone client, so this effect seems limited to the show page view on my Xbox 360, perhaps a useful clue.
