As part of a general balance mod, I am trying to eliminate city states from going to war when allied with a player. I find that in multiplayer specifically, this ends up meaning people lock in their mid game alliances and there is no chance for a diplomacy victory. Does anyone know how to do this? I was hoping there was a line like applying a defense pact to the ally of the city state, but for some reason I can't find it. I tried searching, but I also couldn't find it (or overlooked it - in which case, I apologize!). If anyone could point me in the right direction, I would really appreciate it.
