Recently I installed Civilization 5 with DLC. I love playing the game with spies. But when I encounter that my spy got 'Killed in Action'. I have search the net for this but so far I read the wiki said 'replaced after some turns'. What is the exact number of turns? Is it based on distance of the city? strength/experience of the spy? or fixed like exactly replaced in 5 turns?
Thank you in advance!
