What happens if I genocide the Astari? I killed off the entire Astari village, except for the 21 or so that joined my village.

Their head disappeared from the scale, and I'm a bit afraid that I fucked up.

I killed them with a mix of finger of God, swamp, and 3 or 4 meteors.

Also, even though I haven't expanded that's far, I can now terraform that territory and I used a gem to fill up the farmer village. Is that a glitch or what?
