Bungie community manager dmg04 confirmed a Destiny 2 glitch that redirects Master Lost Sector rewards into easy Tier 5 armor farming will not be fixed.
A full Engram inventory sends Lost Sector drops to the Tower Postmaster, where unopened rewards can turn into Ferropotent, Smoke Jumper, or Techsec pieces instead of the original location set.
Players can trigger the method quickly because Master Lost Sectors also sometimes drop Exotic Engrams, helping fill inventory fast and making repeated T5 farming possible in under a minute.
The exploit matters because Ferropotent and Smoke Jumper are prized 2-piece sets, while all 3 sets are normally harder to obtain through Vanguard Engrams.
A July 7 hotfix is still set to address Vanguard reputation gains in Monument of Triumph, which should ease normal acquisition even as the armor glitch remains available.
