Laravel Eloquent can increment ($collection->increment('field')) fail?

I have a redirect function that looks like this. For some reason, it looks like it's sometimes missing to increment the item. I'm wondering if it sometimes can be so that it misses this because some caching or something?

public function redirect($key)
{
    $item = $this->item->findOrFail($key);

    $item->increment('redirects');

    $encode = urlencode($item->_url);

    return view('item.redirect', ['url' => ($encode)]);
}
