Unmapping is usually to solve conflicts, for example: Season 1 Special 1 from AniDB doesn't exist on TVDB, Season 2 Special 1 does as S00E01, Special 1 on both AniDB entries are naturally mapped to TVDB's S00E01, so we unmap the first one.

Ah, I interpreted "conflict" broader as "If the episode in anidb does not match any episode in tvdb". Probably because that's what I actually needed :flushed:

Not unmapping these specials cause a bit of a problem for me as my use case involves using this list to sort series, and episodes, to a tvdb compatible library if, and only if, tvdb has metadata for it. The tool only has access to the anidb API and this list, so without the unmapping I have no way of knowing if a special episode is not present in tvdb and thus should not be sorted to the tvdb library. I'll have to think about this :thinking:
