So I preordered COD: Advanced Warefare from GameStop just for this shader, and with every intention of canceling the preorder once i've redeemed it (Yes, I am [i]that[/i] guy and I am [i]not[/i] sorry). However, when I finally received the code, it says that it is either invalid or has already been redeemed. I know this was a minor problem prior to Destiny's launch, but I haven't read anything on it post launch and was curious if anyone else was having this issue, or If I've missed something... ...Or if it's just karma, in which case then I guess I can accept that.
