Product Update - Valve
Sep 28, 2011 Patch Notes
• Mac now supports cross platform multiplayer with PC.
• Advanced game settings automatically save.
• Pacing has received a large amount of work. Expect to have more of a challenge managing your empire at higher difficulty levels than you did before. Consider dropping a difficulty level if you have problems.
• Existing saves will work correctly. However, the balance pass may make your existing happiness lower than expected when loading into your existing save post-patch.
• Fixed an issue that was not allowing the Americas building set to display properly.
• If a 3D leaderhead scene cannot be created, fallback to 2D.
• Update to river color, texture, and shader.
• Pre-Game: The tooltips for unique items in the Loading screen no longer show up until AFTER loading has finished, preventing potential “stuck” UI.
• Pre-Game: Prevented escape key from being used to corrupt starting parameters while starting a tutorial game.
• Pre-Game: Multi-player maps added to Single-player as well.
• Pre-Game: Fixed a rounding issue in the options menu so that values are always integer based for the tooltip delay.
• Pre-Game: Using ":" in a save filename is no longer considered valid since Windows does not allow this. Players could potentially use this character in a save name without knowing that the file was not created when they exited the dialog.
• Notifications: Fix notifications that arise after a city is liberated so they show the name properly.
• Notifications: Extra DOF expiration notifications removed.
• Notifications: Notifications for denouncement or friendship are only displayed if the active player has met one of the teams.
• Tool-tips: Tooltips for worker/workboat build recommendations now build dynamically by looking at tile yields for these improvements: camp, pasture, farm, mine, trading post, fishing boats, custom house and manufactory.
• Tool-tip: Plot Mouse Over text for Natural Wonders will now display the culture yield as if it was in your borders and being worked, similar to how other yields are displayed.
• Mod Browser: Mod Browser panels now reset their scroll value when a new mod is selected.
• New Addition: Resource Panel integrated into upper-left Info Panel UI.
• New Addition: Specialist slots in buildings are now shown in the info tooltip for both the tech tree, production popup, and Civilopedia.
• Combat Preview: "Bonus VS Cities" is now renamed to "Penalty VS Cities" when it's < 0.
• Combat Preview: Fix bonus display issue when bombarding an enemy unit (if enemy had bonuses that required “friendly” territory, it would show up in the preview even though they were obviously in enemy territory).
• Combat Preview: Show Oligarchy Garrisoned Unit bonus for city ranged attacks.
• City Screen: City Growth meter within the City screen now displays the correct amount.
• City Screen: Fix the display of the current research progress UI, which made research estimates appear to be incorrect.
• In-Game: Fix the display of the movement cost for units that can embark.
• In-Game: Fixed a rounding issue in the military overview (actually, a lack of rounding issue).
• In-Game: Properly hide the Aircraft selection UI if hidden from view (fog of war, etc.).
• In-Game: City State's "Quest" icon is now hidden if that City State is at war with your team.
• In Game: City banner now displays different tooltip for puppet cities that are not owned by the player.
• In Game: Top Panel now differentiates between unhappiness from regular population and unhappiness from specialists.
• In-Game: Selecting a unit in the military overview will now select that unit, selecting it twice will now move the camera to it.
• Victory: Fix UI display of Diplomatic Victory votes (it was displaying votes from dead Civs/City States).
• Victory: UN Voting and Results screens now have better support for team games.
• Multiplayer: Human players no longer show an approachability type since that was meant for AI.
• Multiplayer: Multiplayer diplomacy w/ teams no longer has overlapping text.
• Diplomacy: There's now a confirmation dialog when you publicly denounce a civ.
• Diplomacy: Player cannot publicly denounce a civ multiple times in the same turn.
• Unit Panel: Fixed an erroneous display of a needed upgrade resource if the needed resource quantity was 0 and you are running a deficit on that resource (negative return value).
• Production: In UI for national wonders that have a prereq building, don't list each individual city that needs the building if the prereq doesn't have to be in EVERY city in the empire. Instead just continue to show the count.

• Civilopedia: Multiple updates to Civilopedia functionality and accuracy.
• Pre-Game: Civilization Name in Load Menu is now truncated if it's too large.
• Civilopedia now available in the Main Menu (under “Other”).
• Replay is now available at the end of the game, and through the main menu. You can choose Map, Graphs, and turn-by-turn. Only game played post-patch will apply.
• Great People progress UI addition (upper-left Into Corner UI).
• Combat preview for Aircraft UI addition.
• Fixed aircraft UI issue causing the aircraft selection UI to duplicate itself when rebasing aircraft.
• When loading save game files, you can now order the list by name, or last modified.
• Fix aircraft UI bug that was causing Nuclear Missiles and Atomic Bombers to leave behind container UI after it’s destroyed.
• Removed dead players from Demographics UI.
• Don't allow research agreements if one party has finished the tech tree.
• Correct opinion code so we can get outcomes of friendly or allied.
• Fix the AI's deal adjustment so that it doesn't accidentally treat your luxury items as strategic items. This essentially prevented the AI from ever countering the deal with a request for a strategic resource from the other player. It just re-submitted the counter offer, requesting more luxury items, which the player could not see. If accepted, the player would realize too late that all their luxury resources were gone.
• Made backstab routine more transparent (the dialog will clearly state that they are backstabbing you).
• AI now remembers when it has been nuked, for a permanent diplomatic penalty.
• AI now recognizes a player that captured their capital for a permanent diplomatic penalty.
• End declaration of friendship as soon as war is declared (so can’t later get a notification that is has expired).
• AI remembers if you satisfied one of their requests (positive modifier, decays over time, based on value of items granted).
• AI remembers if you fought against a common foe (positive modifier, decays over time, based on damage done to the common foe).
• Track trades between players and allow that to positively influence relationships (the better the deal for the AI, the stronger the modifier). Particularly useful for bribing a hostile AI.
• Economic AI: Tweaks to improve the number of workers built.
• Diplo AI: Correct minor error in calculation by AI to decide if it wants to join a coop war.
• City Strategy AI: Fix flavor broadcast to cities just after they are founded. Player level adjustments since start of game weren't being copied over to the new city.
• Operational AI: If AI sees that WarState is Calm (i.e. no one has troops near enemy lands), still consider launching an attack if overall military strengths are at least even.
• Operational AI: Enhancements to more sensibly pick city from which to launch a naval invasion.
• Operational AI: Slightly relax requirements for naval invasion to be on target (to get them onshore and attacking sooner).
• Operational/Tactical AI: Fix to movement/deployment for naval invasion forces.
• Operational/Tactical AI: Improved weighting and selection of muster and target cities for city attack operations.
• Tactical AI: Early game AI tweak to allow occasional sneak attack.
• Tactical AI: Improvements in civilian and embarked units targeting.
• Tactical AI: Units with defensive embarkation had a combat strength when embarked and were being considered for tactical moves (like making ranged attacks) that they weren't actually eligible for.
• Tactical AI: Improved the logic of how units are chosen for tactical moves so embarked units can now drop into place on land as flanking units, bombard units, etc.
• Tactical AI: Changes to more effectively use Great Generals offensively.
• Tactical AI: Citadels now project danger.
• Tactical AI: Units defending citadels are high priority targets; AI will prioritize trying to take these spaces.
• Tactical AI: AI will now pillage undefended citadels.
• Tactical AI: Be wary when approaching an enemy city; don't close on it if enemy clearly has superiority.
• Diplo AI: Make sure the diplomacy AI doesn't declare war on someone they are already at war with. Prevents confusing pop ups.
• Operational AI: AI will now correctly abort operations against a player that were started during a war (like gathering a new attack), but could execute after a peace treaty was declared. This corrects the occasional “AI declared war during a peace treaty” issue.
• Operational AI: Fix muster radius for gathering a naval invasion. Invasions won't get stuck trying to gather and will get moving to target sooner now.
• Operational AI: Don't allow nuke attacks on tiles that will break a peace treaty.
• Homeland AI: Make sure that flavor settings don't prevent workers from building improvements. This would cause some AI players to have large amounts of unimproved space in later parts of the game.
• Homeland AI: Fixed a problem that was causing workers to ignore pillaged non-resource and bonus resource tiles.
• Rebalanced AI flavors and strategies for unit training to improve AI army composition and build choices.
• Allow the AI to consider Pikeman units for offensive roles when they can’t build Swordsman or Londswordsman.
• Allow Alexander and Darius to consider Hoplites and Immortals for offensive roles early game.
• AI players may now use a Great General in early rushes on higher difficulties.
• Modified flavor tags for Atomic Bomb and Nuclear Missile so AI builds them only when it decides it specifically wants Nukes.
• Block City States from building carriers, atomic weapons.
• Strategies for building mobile units now persist into Modern era to help AI decisions for when to build tanks and modern armor.
• Damped early game Grand Strategies to give the AI time to expand (AI were sometimes stuck in a single city until late in the game).
• Victory adjustments to AI behaviors, including alternate victory paths as “back-ups” (for example, building the Apollo Program, even if they are not going for a Spaceship victory).
• Revise code calculating recommended army size (using smaller armies if the threat is low).
• Correct issue that was causing late0game continent-bound AI’s to over build units intending to invade, and never properly execute the amphibious invasion.
• Scale recommended army sizes based on difficulty level.
• AI grand strategy and flavor weighting balance pass.
• AI policy choice weighting balance pass.
• AI tech choice weighting balance pass.
• Units: Stealth Bombers can now get promotions.
• Units: Add “Fortify until Healed” option for aircraft. Before, they only healed when inactive, which could cause confusion for the player.
• Units: Prevent units with the "No Melee" promotion from capturing cities (archers, catapults, etc.).
• Units: Air units must be in a city to upgrade, and no sneaky "I'm on a carrier in the city" either.
• Units: Fixed a problem that was allowing units to upgrade in territories that were not their own.
• Terrain Improvements: Allow Moai to be built over top of resources.
• Terrain Improvements: Correct an issue that resulted in double resources if you founded a city on top of an improved resource plot.
• Yields: Fix a load order problem where the lake bonus is not applied to a farm after loading an existing save.
• City Management: When selling a building, ensure that all citizens are properly removed.
• City Management: When assigning a specialist to a building, make sure we don't accidentally assign more citizens than we have available.
• City Management: Fix for an issue that was causing workers to go missing when population went down.
• City Management: After the citizen is removed from working, adjust the unassigned worker count before subtracting from the total population. There were rare situations that could cause the worker to disappear.
• Culture: Keep the current culture level of the city after it is captured. The culture production will go to 0, but the culture level must remain the same or else a large city will be able to acquire tiles at the same rate as a smaller city.
