I can confirm the issues with the Vassalage system. I have seen the AI become a vassal to another AI civ very early in the game for no apparent reason. In the Advanced Setup options for a new game you can disable Vassalage. This is what I am doing in all of my games.I got a couple of questions regarding the current state of VP. My last games on the recent patch (as of yesterday from this post) had some weird gamebreaking issues for me and I wonder if that is intended or not.
a) AIs will >peacefully< become vassals of another AI even though they are ~equal in almost all categories (military, science, #cities, etc.. ). That has completely ruined two of my games already, since the faction was then way too strong and steamrolled all remaining AIs.
b) Does the player get warmonger points for AIs declaring war on him? In my most recent game my warmonger score keeps snowballing up since two AIs declared on me early on and I took one(!) city of one of them. Now AIs just keep declaring war on me and I sit on ~250warmonger score with some of them, north of 90 with all. I mean.. wth?
This kind of irrational behavior seems wildly broken to me and is no fun to play with at all.
Cheers,

The warmonger system is unfortunately a poor design choice by the authors of the game in the way it was implemented. You get war declared on you and then you are penalized for attacking and taking their cities. In my opinion there should be no penalty unless you were the civ to declare war. It would require a major change in game design to fix this so I don't expect this mod to address this issue directly.
