There was a problem with it at the beginning. I saw Frank mention in the SB it would be given manually, so if it hasn't already I'd send in a support ticket asking for it and they'll be able to give it to you.
Hi thehippi and Kinera. I believe that you guys already have the hidden avatar for the lunar outfit. The alert for the giving of the avie might be not too noticeable. Please check your Forum Preferences to verify. Thanks.
You must be one of the very few people who purchased the item immediately. There was a problem with the avatar so I had to fix it and manually give the avatar to those who have purchased the item before the fix.
