Unable to download Tate no Yuusha no Nariagari episode because of incorrect Guessit parsing

[sam5558]

Hello,
First of all thank you for this project, i love it.

Describe the bug
The issue i'm facing is that i'm unable to download the following file (Tate no Yuusha anime) :

[[Tsundere-Raws] Tate no Yuusha no Nariagari Season 2 - 03 VOSTFR (CR) [WEB 1080p x264 AAC].mkv](https://nyaa.si/view/1517376)

After some diagnosis i found that pyMedusa is having hard time identifying the season... It should be Season 2 => S02 but for some reason Medusa was identifying it as Season 3 (basically took the episode number as Season number).

After removing / adding the same series with a new indexer (from tvdb to imdb) i did the same exact test and now it identifies the episode as Season 02, 03 (basically two seasons for the same entry...
Result :

{
    "title": "Tate no Yuusha no Nariagari",
    "season": [
        2,
        3
    ],
    "subtitle_language": "French",
    "release_group": "CR",
    "source": "Web",
    "screen_size": "720p",
    "video_codec": "H.264",
    "video_encoder": "x264",
    "audio_codec": "AAC",
    "container": "mkv",
    "type": "episode",
    "parsing_time": 0.021677017211914062
}

Medusa is then discarding the result :

Discarding result. Multi-season detected for '[Tsundere-Raws] Tate no Yuusha no Nariagari Season 2 - 03 VOSTFR (CR) [WEB 720p x264 AAC].mkv': MatchesDict([('title', 'Tate no Yuusha no Nariagari'), ('season', [2, 3]), ('subtitle_language', <Language [fr]>), ('release_group', 'CR'), ('source', 'Web'), ('screen_size', '720p'), ('video_codec', 'H.264'), ('video_encoder', 'x264'), ('audio_codec', 'AAC'), ('container', 'mkv'), ('type', 'episode'), ('parsing_time', 0.09723186492919922)])

Additional context
I tried using the scene exception like this :

But didn't work also.
PS : I also removed the cache.db in case it kept old entries or something problematic, still won't work.

Thank you for your help.

Yeah this is an issue with the Guessit parser.
You can report it here: https://github.com/guessit-io/guessit/issues

I could try writing a rule for it. But tbh guessit should be able to recognize this as a titel - episode format.

Added to this issue: guessit-io/guessit#690

I've added a rule myself. Should be fixed shortly.
