The Lavaland Botany Ghostrole "Preserved Terrarium" is intended to have a full setup to be able to play around with botany relatively easily.
Unfortunately, the Botany Rework added the need of the seed sorter when plant mutations are being done and the previously mentioned "Preserved Terrarium" Ghostrole currently lacks the seed sorter.
I have also noticed that the Syndicate Outpost Ghostrole also lacks a seed sorter. This role needs it as being able to play around and figure out the various things on the Outpost such as Botany.
In short: Add one or more seed sorters to both the Preserved Terrarium Ghostrole and Syndicate Outpost Ghostrole.
