Bug on order status change on backoffice

[yourzed]

Hi, I have the prestashop version: 1.7.2.1.

The shop is working as expected, but sometimes, on specific orders, It doesn't let you to change the order status. It gives a generic error, and on the logs it doen't say nothing. I have been debuging the code and I found that it all works until:

Hook::exec('actionOrderStatusUpdate', array('newOrderStatus' => $new_os, 'id_order' => (int)$order->id), null, false, true, false, $order->id_shop);

On the /classes/order/OderHistory.php

The $new_os variable has the object correct and the $order variable also....

Any ideas?

Thanks
