I just ran across your mod last night, and it looks great. I was really enjoying it. There were a few peculiarities, but for the most part it was stable for me. One thing that I've found that is potentially game breaking for me, or at least annoying enough for me to stop using the mod is diplomacy in general, and religion as it relates to diplomacy.
In my game I'm playing the Shoshone and I'm in the center of a Pangaea (Huge map, Warlord, Marathon). I have gotten several Great Prophets coming and converting my capital. The ones from Hostile nations are deserved, but I've gotten one from a Neutral, and two successive ones from a Friendly. At first I was annoyed, but just rolled with it, but when I protested to the Neutral and Friendly they said they wouldn't send their missionaries in any more, and then proceeded to immediately convert another city. I've never seen this happen.
Another detail that indicates for me that the problem might be in the diplomacy section of the mod is that the AI is incredibly volatile. I've had nations go from Friendly to Denouncing with the two diplomacy actions listed as Made friendships with the same nations and We denounced you. The next turn they were hostile.
