AI Units won't disappear if there was never a city

[samspock]

I played a tiny map game where my starting quecha was next to an AI's starting stack of settler and two warriors. On turn one I moved north one square towards a goodie hut. The AI moved the settler to the goodie hut but could not found a city since it was two squares away. The wariors went in other directions leaving the settler unguarded. I attacked it giving me a worker on turn 3! The to warriors did not dissapear! They kept on exploring. I ended up killing them later.

I guess to get rid of everything the ai player has hanging out there after they are killed off requires that they had a city first.

I think they got a new settler somewhere else

Nope. I killed the two warriors and they were gone.
