Could your PM(preferred since they have your personal data) or post log or find me on IRC?Unfortunately it still seems to download already watched episodes... At least with "new episodes", didn't test "missing episodes".
Also, log is still full of entries like this (seems like a lot of searching for nothing):
How did you add new series? There are two options "Add series" and "Search series". Adding is perfoming through mptvseries db and you will have unwatched episodes for show. Searching is done through trakt and I just realized that new epiosdes will be always empty since I forgot to write request to trakt to make it.
