Was playing a game today as Poland, got stuck on a small continent with William. We both founded a religion, although he went piety. After converting a couple of my cities I asked him to stop spreading his religion and he agreed, only to do it a half a dozen more times, taking me to 0 cities of my own religion. After a while my Holy City went back to my religion and I was able to get an inquisitor up. My question is did William receive negative diplo modifiers for breaking his word to me? He never got denounced. I did end up wiping him out entirely out of frustration, but we were at one point in a DoF during some of what was a very chaotic game (Zulu, Japan, Babylon, and Soshone). Or is the hit so minor that it wouldn't likely be the sole cause of a denunciation?
