Everyone is losing their deluxe content so join the club. Uplay is buggered up, and has been for some time now. So if you get another key the chances are your deluxe content will go missing again.
I have had a ticket in for weeks now, and all that I get back is BS, WAIT/HOLD and similar. The support is near none existent.
Letters have been sent to magazines and game site, and petitions started, in order to get some response from Ubisoft on the situation.
Thx, Ubi!
For my part Deluxe contents has returned on screen! I hope it stays like that
