Total Diplomacy is not optional (the scroll simply present you with the fact that TD exist).
Why not optional then? Because all of Total Diplomacy's features are self-activated, a.k.a only kick in if a player chose to use them in-game by buttons or key-combinations.
Self control, people, you're not Laura Branigan 
And please ask submod-related matters in their respective thread, in this case the MOS-thread

If they be your vassals you will get all their money or such. I can't remember how much they can have before you start to get money.
IIRC a vasall give half their income each turn to their lords
Aha! Yes I have :') funny how you should guess that!
problem solved then that it is my own fault.
However is there a way to take this mod out anyway as I shouldn't technically have been able to make them vassals aha
Keep your hands on the top of the sheet mister
