Prestashop 1.6.1.1 One page checkout - for orders placed at the same second, one of the addresses is not saved in the database

[gmanPrestashop]

Hello,

I have the following problem that I can easily replicate:

Whenever I have 2 orders placed at the same second, using One Page Checkout PS, Cash on Delivery Module for example (but it happens with other payment methods as well), for one of the customers, the address is not saved in the database.

In Admin Back office one of the 2 customer will have the other customer's address associated.

In the database, in ps_orders I have 2 different orders with the same id_address_delivery and in ps_address there is only one new address saved.

Did anyone else have this issue?
