How to replace base farmer, armourer, and scientist?

[Arland]

I already have hired all five base NPCs...
Now I wish to replace them for some more colourful and more interesting looking ones...
I am searching in space stations... no matter which one I go to, I always end up only finding the overseer and the technician (back room diagonal from the space station teleporter).

Where must I go/what must I do to find new farmer, armourer and scientist?

Like said, I already hired all five of them once. But my logic is hopefully correct in that if I can replace the overseer and the technician, well then there should be some location somewhere also where I can go to get a new farmer, a new armourer, and a new scientist?

I find them at trading posts on planets, also at space stations in the back room.

They're out among the general population of the station now.

I noticed today that the teleporter still has the farmer listed where I originally hired him. Maybe you do to.

I tried searching some more... then I gave up and just generated new seeds with save editor until I was happy with the appearance of my crew.
So if anyone else is looking for a solution for how to alternate the way that your NPC squad looks, that is one way to do it.

There are so many of the "desk" dudes around in stations or trade outposts I'm getting annoyed sometimes lol....
