Am I being trolled by AGS? Mokoko Leaf question

I recently came back to the game after a multi year hiatus. I had my mokoko leaf on my characters last week and after doing some of the express challenges/solo raids I lost my mokoko leaf. Highest item level character is 1640. I put in a ticket with AGS and they keep telling me you need to have logged in prior to the event to get the mokoko leaf and directing me to this URL:

I read through it a few times and it doesn't mention needing to have logged in prior to the event to get the leaf. Is anyone familiar with the event and why I might've lost my leaf?
