I've been listening to these extremely helpful podcasts for a while now, and it's always updated the same podcast subscription. However, starting with Survival Phrases #26 on June 19th, every time a new episode downloads, the previous JapanesePod101.com podcasts show up with the exclamation point icon, and a new JapanesePod101.com podcast subscription appears. The new episode still downloads, but I'm getting a growing list of bad podcast subscriptions with just one episode in them (5 now), except the original one which contains 80 or so episodes.
Any idea what might be going wrong? I'm using Mac OS X Tiger, if that helps.
