I noticed the Accor Plus FAQs got updated with a question about when will the 20 nights upon renewal be credited: "The Status Nights bonus will be reflected in your account within a month of your effective joining or renewing Accor Plus membership subscription date."
May or may not be an issue for those who have renewal dates during December, since in theory the crediting might not occur until the January (new calendar year)
