Hello, I'm really sorry about this, but to be honest, I have no idea where the issue comes from. I've completed 64 giveaways with only a tiny handful of errors, even though the keys have never been used. I don't know what’s causing this problem, and unfortunately, I have no way to fix it.

My sincere apologies once again...

Would it be possible for me to delete this giveaway?
I need to launch new ones, and I hope you'll join again for a chance to win another game.

Once again, truly sorry.

Patrick
