Hmm, but that's not how the game works, on any map. I think you're mixing up second time Gifts versus the first one you're supposed to get for map completion, like every other map, including the 2 other ones used with this gift, which also have lamps.
Are people that didn't complete half the map before the update and complete it all now going to get a Gift of Inner Nayos? If so, everyone who completed the map before should get one when they finish the full complete.
Punishing the early adopters doesn't really make sense. The lesson learned here is don't engage with unfinished content. Not a very good message to be sending to people.
:EDIT:
I didn't realize the map was actually still incomplete, so although it's confusing due to the lack of communication about the situation, this temporary solution of doing something that's never been done before to get the first gift of [map] is clearer.
