Sitting Bull (native American) was + 7 with me, 1 point for peace for many years, another 6 for being the same religion. -1 point for having close borders. But then I refused him Compass when I just got it, he wanted it for me. Then I got -3 for that alone. Some turns later and he declare war on me with the Inca's. It's unreal isn't it, how can the situation turn around so quickly?
