Has anyone else experienced what, for me, feels like a bug in the game? Someone sends a prophet or missionary into your territory and starts converting your cities. You ask them not to do it any more and they agree, but they keep doing it any way! Unlike in spying there doesn't seem to be any recognition that they broke a promise they made, they just keep on doing it, and the only way I can see to stop them is to declare war on them and forcibly take the proselytizing unit to destroy it.
Or is this just civ being civ?
