Laravel Revisionable not storing updates to model

I have a web site that has a really big form that is stored across many different models. I wanted to implement model history, so I could know which user modified one of these models. I started using VentureCraft's "Revisionable" (http://ift.tt/MGRljz), as they already use this.

I configured everything as the documentation says, but the only change that is recorded in my model is the "created" one. If I modify any field other field, the changes are not stored on the "revisions" table in my database.

Here's my model that uses the trait:

namespace sonda\Models\RFC;

use Illuminate\Database\Eloquent\Model;
use Venturecraft\Revisionable\RevisionableTrait as RevisionableTrait;

class Rfc extends Model
{
use RevisionableTrait;

public static function boot()
{
    parent::boot();
}

protected $revisionEnabled = true;
protected $revisionCreationsEnabled = true;

protected $keepRevisionOf = array(
    'client'
);

protected $guarded = [
    'id'
];

public function areaParticipants()
{
    return $this->hasMany('App\Models\RFC\AreaParticipant');
}
public function involvedMachines()
{
    return $this->hasMany('App\Models\RFC\InvolvedMachine');
}
public function areaNotifys()
{
    return $this->hasMany('App\Models\RFC\AreaNotify');
}
}

You can see here: http://ift.tt/1FOnK2g that it is not entirely broken, as the create method is being called and stored in the database. Still, any update or edit is not being kept.

Any ideas?
