I am beyond disgusted with how this quest has been handled . i love the fact that some elbow grease and time is needed for the better exotics in this game but come on bungie. after you apparently "fixed" this quest, my fourth key after inserting into the box disappeared and didn't give progress . now i dont have a quest for a fourth key or a mold and it didn't advance the quest. so now what ? i have to wait another four weeks and re do all the grinding i spent since the "fix" this previous Tuesday . I am so disappointed . You guys need to actually fix this quest or just change the way it's completed at this point . I hope you can track people who have been effected by this and lost their items and fix accordingly to the part we SHOULD be on ..
