It seems that the playlist's automatic episode removal rules are causing it to remove episodes that a user may not want removed yet. In my case, it will remove an episode that has not been finished if I start playing the episode after. For example, episode 1 is 50% played, then I start playing episode 2 in the list. The auto-removal then removes episode 1 even though I wasn't finished with it. That may be by design, but it can be a problem if the user accidentally starts playing a later episode in the list, for example. If I have 20 episodes in the play list and episode 2 gets automatically removed (in this case, because of operator error), the only way to fix the list is to clear it and rebuild it.
