that is the problem, the first event was mushrooms, that event expired, its ok, but im a player that spend only 5 hour a day to get mats for upgrade my weapon to scorpion. and i repeat, i dont understand why the item have to expire, my suggestion is allow us to use that item in the weapon, not sell it for only 5g.... upgrade ur weapon to breeze or scorpion is not easy for a standard player.
