Indeed, i noticed that too but as i'm always playing with a huge lot of civs, having 2 of that kind wouldn't be bad. But your suggestion is fine too. As long as building a wonder doesn't put my empire in unhapiness, i'm will be glad ^.^ Frustrating, but it makes sense. Definitively not. I was writing my let's play so i was going very slowly to take note of everything that happens. Maybe it was the switch between windows and the game that pauses problem... As i usually don't take a religion before late, i will keep alert to see if it happens again or not. Ah, agree ! Was just a misunderstanding on my part then, and i'm glad so. Invincible workers would have been weird indeed. Short answer : trauma. Long answer : did that a few years ago on vanilla, ended up having a stack of doom coming in my way like a hundred turns after the war was launched. Not sure if R:I AI would do something so risky and with so little benefit, but still i'm reluctant to accept war request since then. As always, thanks for your time and your replies !
