Maximum call stack size exceeded

Maybe this is coming from a lack of understanding of how it's supposed to work, but I can't seem to map multiple relationships & use cascadeSave():

var mongoose = require('mongoose');
var cascadingRelations = require('cascading-relations');

mongoose.connect('mongodb://localhost/relationships');

var sShow = new mongoose.Schema({
  _id: Number,    // the key in the other database
  title: String,  // the name
  slug: String    // can be used to get URL, images, etc
});

var sEpisode = new mongoose.Schema({
  _id: Number,     // the key in the other database
  title: String,   // the title of this episode
  season: Number,  // the season
  episode: Number, // the episode
  url: String,     // URL for downloading this
  show: { type: Number, ref: 'Show', $through: 'episodes' }
});

var sUser = new mongoose.Schema({
  email: {required:true, type:String, unique:true},
  watched: [{ type: Number, ref: 'Episode', $through:'watched' }],
  ignored: [{ type: Number, ref: 'Episode', $through:'ignored'  }],
  collected: [{ type: Number, ref: 'Episode', $through:'collected'  }],
  subscriptions: [{ type: Number, ref: 'Show', $through:'subscribed'  }]
});

sUser.plugin(cascadingRelations);
sEpisode.plugin(cascadingRelations);
sShow.plugin(cascadingRelations);

var User = mongoose.model('User', sUser);
var Show = mongoose.model('Show', sShow);
var Episode = mongoose.model('Episode', sEpisode);

var user = new User({email: '[email protected]'});

var show = new Show({
    _id: 481,
    title: 'Game of Thrones',
    slug: 'game-of-thrones'
});
show.save();

user._related = {
    subscribed: [show]
};

user._related.ignored = [
    {
        "_id": 45305,
        "show": 481,
        "title": "Game of Thrones S03E09 HDTV x264-EVOLVE",
        "season": 3,
        "episode": 9,
        "url": "magnet:?xt=..."
    },
    {
        "_id": 44337,
        "show": 481,
        "title": "Game of Thrones S03E05 720p HDTV x264-IMMERSE",
        "season": 3,
        "episode": 5,
        "url": "magnet:?xt=..."
    }
];

user._related.collected = [
    {
        "_id": 55200,
        "show": 481,
        "title": "Game of Thrones S04E06 HDTV x264-KILLERS",
        "season": 4,
        "episode": 6,
        "url": "magnet:?xt=..."
    }
];

user._related.watched = [
    {
        "_id": 43700,
        "show": 481,
        "title": "Game of Thrones S03E02 720p HDTV x264-IMMERSE",
        "season": 3,
        "episode": 2,
        "url": "magnet:?xt=..."
    }
];

user.cascadeSave();

I get this:

...node_modules/cascading-relations/node_modules/q/q.js:514
    var deferred = object_create(defer.prototype);
                   ^

I am trying to map this relationship:

Just from your diagram it looks like you may have recursion going on. I didn't consider that when creating the package as I traditionally used it for hierarchical relations.
