So apparently Gifting a bundle doesn't count for this one, As all the bundles I purchased were gift copies, I don't see this in my account... I wonder if I should contact their support.
probably - supposed to be for gift buyers too I believe... unless you bought without an account!
Well I finally got a response after a week of corresponding with details and whatnot:
You don't have a copy of the giveback bundle because you did not redeem any of those gifts in time. People that get the gifts got the free copy of the bundle not the individual that purchased the gift. Sorry about that. Let me know if there is anything else I can do for you.
Seems a bit miss-leading to say the list, considering they clearly said in the description:
If you purchased
or were gifted a Groupees bundle in the past 12 months, then you’ll find this bundle in your profile.
