Easier Confederations & Vassals

Annoyed that your best buddies don't like to confederate you for whatever reason? This mod significantly increases your chances of confederation and vassalage when you're best friends (150+ relations). This should help AI factions confederate each other more too, but it's not guaranteed because AI decision making is different.

This mod can be turned on or off whenever you want, just remember to click the "Enable all saves" checkbox so you are able to load your save with a missing mod.

Confirmed to work in multiplayer by multiple people in the comments, I'm taking their word for it.

This mod does not add or remove any diplomatic options, it just makes confederation and vassalage easier. If you're missing options or see additional ones, it's caused by other mods or because of an incompatibility with another mod.

Adjusted values:
Baseline value at 150+ relations ("Trusted Friends") is set to 0
Baseline value at 50-149 relations ("Very Friendly") is set to -50
Penalty to confederation if the target faction captured territory within the last 7 turns is set from -30 to 0 (thanks, dfnamehere!)
If you are the main threat of the target or have a common main threat, you get a +10 bonus to the deal.

Known issues:
Incompatible with mods that affect the same lines in the following two tables:
cai_personality_deal_evaluation_components, cai_personality_deal_evaluation_deal_component_values

Credit to Reddit user dfnamehere for telling me in this thread about more modifiers, specifically the penalty to confederation if the other faction recently captured territory. That should make confederation a lot more reliable for people.
