I have access to all my Twitch Drops, with the exception of the Gelid Throne (the latest drop). They can all be crafted or spawned using the admin panel (in Single Player, didn’t try on official server yet), but the latest drop can only be spawned in using the admin panel, it cannot be crafted in my Inventory or at the Artisan’s Table.
Edit: I just tested on official server, I am still able to craft all other Twitch Drops, but not the most recent. As @Grymm stated, it is not listed under Ancestral Knowledge.
