Logged on after not being on since the Haunted Event and it seems that Bungie deleted all my helms for masquerader's masks, so I no longer have any 5 star helms that I previously obtained. They are also all 0+ light level. They weren't masks, they were other obtain armor sets. I logged on and they were all the sudden all masks.... Meaning they were not masks to begin with and now they are... They can't be used, my original helms were transformed into masks and are now useless.
