Having just finally got the Sleeper Simulant catalyst, the last catalyst I needed, do I need to complete ALL the requirements prior to the vault date, or can it be completed afterwards. For example, obviously the fact that it only drops from the prestige Spire of Stars on the Leviathan will make it impossible to obtain in the first place once the Leviathan is vaulted, at least until an alternative is made available. Then, there is the fact that you need to do the chests and the Oracles in the heroic Whisper mission, also being vaulted, to progress to the last step of the catalyst. The last step requires you to get 500 kills with the weapon itself to finish the master working of it. If I get the catalyst to that final step, which isn't bound to any content that is being vaulted, will I be able to finish it once Beyond Light launches, or do I need to finish it completely prior to that date?
