I just referred to a friend and they placed their order, my loot box is showing expiration 7/30/22, thats over a year from now. I have multiple referrals. it appears and I could be wrong, that when you refer and its confirmed order, the latest referral extends all your prior miles vs each referral having their own expiration date. also why is it going out to one year vs 6 mo's as stated on the site, anyone else have 1 year extension or recently referred and got a year expiration?
