我知道这个mod使附庸颜色错误的原因了。
mod制作者填写的附庸颜色数值错误，修改数值就可以恢复正常。参考游戏本体的附庸颜色数值
VASSAL_COLOR_LORD_PERC: 0.86,
VASSAL_COLOR_VASSAL_PERC: 0.14
ps：不要试图删除相关代码，会导致附庸颜色错误

To be honest, I wanted vassals to be more than just a way to make money, like asking them to join a war or take on more responsibilities... Thanks for the modification, it's helpful.

I do not know why but this mod breaks the game, as in when i subscribe to this mod all vassals just change their colour to white and i do not know why.

It's in the desceiption @dannyrich164

What are the different stages?

nice
