Not save-game compatible.

General Changes

• Global Peace Accords now grant +1 Delegate to all Civilizations at Peace with all Major Civilizations.
  
• Casus Belli now grant +1 Delegate to all Civilizations at War with any Major Civilizations.
  
• Granting +1 Delegate is now appropriated per 40 Population instead of 35 Population.
  
• United Nations grants only 1 delegate passively to all non-host members when the United Nations is constructed rather than 2 delegates.
  
• Removed the Sphere of Influence penalty until further notice. (Tooltip still remains, but does not harm gameplay)

General Changes

• Reworked Host and Member delegation system.
  
• Puppeting a City-State now acquires you the option to liberate it(You get no warmongering penalty deducted since you conquered it!)
  
• Choosing the Sphere of Influence on a City-State will now incite a revolution! (If a revolution becomes successful, global peacekeeping forces will put it down and respect your sphere of influence nonetheless the revolution can pose a threat to civilizations who are attempting to subdue their enemies' allies!)

Fixed a few bug involving liberating City-States.
Fixed art assets involved with the five new projects.

Not save-game compatible.

Fixed AIs not installing proper sphere of influences and open doors correctly.

SAVE-GAME COMPATIBLE DO NOT START A NEW GAME BECAUSE OF THIS UPDATE

Reworked Voting Mechanic System: Every 35 population(including puppeted) = 1 vote and +2% Unhappiness. No questions asked. There will be no more bonuses due to having a larger population. Just votes and national unhappiness increases.
Optimized Lua code for faster processing (Every seconds count!)
Fixed an issue when liberating multiple city-states on one turn would prevent you from setting multiple sphere of influences/open doors in the same turn.

Not save-game compatible. I recommend to update. The voting mechanic is simple and favors both tall and wide empires!
