Was there tweaking on diplomats, to make them easier to bribe? Or to lower the cost of bribing overall?

As Sicily, I've lost every diplomat to bribing. To the Moors. The only way for me to maintain diplomatic relations with other factions is with my princess. Every diplomat that leaves the safety of my settlements gets bribed within a turn or 2. And Italy is now flooded with Norman named Moorish diplomats.

If this has been tweaked... what is the rationale? Would just like to know the basis of change.

Great mod! I've been unable to expand with ease and I would like to thank Lusted for the challenge.
