The silver tier (yeah I know I’m 1 pt away from gold 
) prize for 25 ribbons is a BFZ booster. BFZ is no longer in the vault. How can this be redeemed?
Or for those who’ve already got it, what did you get instead?
There have been plenty of other times that packs were given for things not in the vault. If you have one for it, it shows up there to be redeemed, then the banner for it goes away once you do.
