I took a missionary to Paris and tried to spread religion. Straight away the leader was annoyed and asked me not to convert any more cities.
No problem. I am going for a cultural victory and war is the last thing on my mind.
So I continue to spread religion among my own cities and somewhat distant neighbours of France.
However, after a few turns it seems I have broken my promise.
None of France's cities show anything but their Parthenon icon.
Is this something that is bound to happen all the time? To a certain extent I cannot control my religious influence.
Next time I know. Don't convert France to have them ask to stop converting.
For worse (or much better). Kongo is spreading the religion for me to France. Could they have broken the promise as a proxy? I did not spread religion to France using religious units and I'm confused to how I broke my promise.
