ModelFactory is not generating $ faker data for some tables

I've been using the default% Laravel 5% for some time, and everything was going ok, but for a few days now I've stopped generating data from the ModelFactory library for some tables, although it's still normal for others.

When you start faker with the definitions below, the php artisan db:seed -vvv table is filled correctly, with all values, and the client table ends with 100 lines of default or empty values.

Any ideas on where to begin debugging this?

database / factory / ModelFactory.php (default)

$factory->define(App\Client::class, function ($faker) {
    $origins = DB::table('origin')->lists('id');
    $methods = DB::table('entry_method')->lists('id');
    $image = str_replace('public', '', $faker->image('public/img', '100', '100', 'cats'));
    return [
        'name' => $faker->firstName,
        'middlename' => $faker->lastName,
        'lastname' => $faker->lastName,
        'birthday' => $faker->date(),
        'type' => $faker->randomElement(array('nao-associado','patrimonial','cooperador','coletivo','entidade','emerito','individual')),
        'associate_code' => $faker->randomNumber(),
        'identification' => str_random(20),
        'identification_type' => $faker->randomElement(array('rg','cpf','cnh','passaporte','social-security','outro')),
        'language' => $faker->randomElement(array('pt','en')),
        'foreigner' => $faker->boolean(),
        'image' => $image,
        'vip' => $faker->numberBetween(0,1),
        'id_origin' => $faker->randomElement($origins),
        'id_entry_method' => $faker->randomElement($methods),
    ];
});

$factory->define(App\Email::class, function ($faker) {
    $clients = DB::table('client')->lists('id');
    return [
        'email' => $faker->companyEmail,
        'type' => $faker->randomElement(array('pessoal','comercial')),
        'id_client' => $faker->randomElement($clients),
    ];
});

database / seeds / DatabaseSeeder.php

use Illuminate\Database\Seeder;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Connection;

class DatabaseSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        Model::unguard();

        DB::statement('SET FOREIGN_KEY_CHECKS=0');

        factory('App\Client', 100)->create();
        factory('App\Email', 100)->create();
        // create
        DB::statement('SET FOREIGN_KEY_CHECKS=1');

        Model::reguard();
    }
}

app / Email.php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Email extends Model
{
    public $domains;
    public $timestamps = false;
    protected $table = 'email';
    protected $fillable = ['email', 'type', 'mailchimp_id', 'id_client'];

}
