My husband's cremello steed didn't work -- it said the code was invalid. So, I tried applying his code and mine to his account several times. Eventually one of them went through, even though it claimed he was granted a Raven cloak. Unfortunately, in all the copying and pasting, I lost track of which one we finally got to work. /headsmack There was no email confirmation that it activated, but he does now have a cremello steed. We're still short one code, but I did reply to the email, so hopefully when Sapience isn't swamped, we'll get a replacement. Anyway, long story short, if you try it more than once, you might get lucky, and make sure to check in the game in case it really did activate.
The title codes all worked on the first try, no problems there.
Thank you for the goodies!
