I've opened numerous large and small mystery boxes from this event, but have received no tokens (themed prizes) at all. Is anyone else experiencing this?
A Little piece of advice, it's better to only open small boxes. Small Boxes give three items each, while larges give five. But, you can get two small's for the price of a large, so you're getting one extra item each time.
As for you not receiving any tokens, it's all RNG. Keep on opening, you'll get a token or two eventually
