My Lightfall Collector's Edition unique postcard code gave me the wrong emblem? I've searched everywhere, and I can't find any explanation. My understanding is that Jade's Burrow is one of the universal codes that doesn't expire, and yet my unique code (which does not match any known code) gave me the Jade's Burrow emblem that everyone already has access to? When I try to redeem the other Jade's Burrow code that everyone has access to (the one that is different to mine), it gives me the "code already redeemed" error. Have I been given a wrong code on my postcard?
