I don't really know how to say this but for some reason I had genuinely no issues with this quest line, I was unable to claim the key mold directly from Ada-1 but i was doing a sherpa for leviathan raid and when we were doing the underbelly I was getting "watcher lenses" and all of a sudden in my quest tab on the very last page I kinda just had the step sitting there. I don't know of I was the only person to experience this and I really don't understand why this happened, I wish I did so I could help with a workaround of some sort. i think I may have un-intentionally found a workaround without realizing however I do fully support this idea, not only did the quest for one of the most demanded late game content weapons become locked behind a poorly designed time-gate with the now rotating daily forges (which was a terrible choice IMO) it also involves RNG for a bounty. (also dumb IMO) The way I see it is if you want an exotic to involve RNG make it an RNG drop, its rewarding to get and its the main driving point for various activities. However if you make an exotic a quest then its a QUEST, meaning there are set in stone steps which the end result is the exotic, dont mix the two.
