I have pre ordered FFXIV HEAVENSWARD collectors edition on day 1 and received my early access code at the same time. To my surprise , today checking my emails I received another early access codes. Now I have 2 of them and they are both completely different. is this normal ? Am I the only one who got 2 Codes? Is the first one that got sent out to me broken? or just a simple mistake?

I'm only asking because I wouldn't like it to be the day of the early access and then I get told that codes are already been used And cannot access the game.

Thanks
