I buy in shop galactic games milestone collection and i don't get heirloom

cidda99​ The main event for it was from August 19th, 2025 to September 9th, 2025, (which is why I said it had ended), although it does appear to be in the game still as the Mythic Heirloom does bring you to its event page, (which that page should end on November 4th, 2025):

While I'm not sure how it works after the main event is over, it should function the same as if the event was actively on going, (where you would need to buy or craft the packs until the Mythic Heirloom is granted).

If you haven't bought or crafted every event pack possible, the chances of pulling the Mythic Heirloom is less than 1%.
