I have all of my podcasts automatically adding to a default playlist. When new episodes are downloaded, they are automatically added- no problem there.
However, if I stop listening in the middle of an episode, and come back to Podtrapper a while later, the episode I was just listening to will most likely have been spontaneously removed from the playlist, and the next episode in the playlist is 'now playing'! Note that the last episode still exists, and is paused where I left it, it's just no longer on the playlist.
Sometimes it's even worse- today for instance, about ten episodes were randomly removed from the playlist.
I'm not sure what could cause this. I think the only settings I've enabled since installing are auto-stop and playback buffering. I also connect and disconnect from bluetooth devices (headset and car) quite frequently, although I don't always use Podtrapper in those cases.
