So i'm currently in the process of unlocking Izanagi's Burden. I opened three of the four locks on the Mysterious Box and all the guides are saying that i need a key mold from Ada in order to start the unlock process of the Black Armory Lock. Unfortunately Ada won't give me the key mold no matter what i do (restart the game, etc.) and i don't know what to do in this situation since i need the mold in order to continue the quest line. I'm aware that the way Forges work was changed with Shadowkeep, so maybe i'm missing something?
