ive run the raid a total of three times. was able to open some chests the first run, then the past two have been discovering that the keys completely disappeared from my inventory (without doing any of what they mention causes errors). i know theyre initially there bc i can open my inventory to check them, but in between going to chests they just grow legs and walk somewhere, i guess bungie better be reimbursing us the keys we lost, or at least giving some sort of exotic engrams to compensate for it. realizing ur keys have vanished after completing the raid really puts a damper on things
