Civilization VI September 2019 Update

The September 2019 Update for Civilization VI was released on September 10th, 2019. The update concerns Gathering Storm only, unless otherwise specified below. The update primarily focused on:
* A new multiplayer scenario
* A number of coast-related adjustments, such as water-based improvements and the Mausoleum at Halicarnassus, harbor buildings and some coastal adjacencies
* Adjustments to some rock band abilities
* Some changes to yields from base improvements
The following is a complete list of change notes.
==Features==
===All game versions: Red Death Multiplayer Scenario===
====General notes====
* If you still have a Civilian unit, then you are still in the game. Once your last Civilian is killed, you will have been eliminated. Be the last remaining player with a Civilian to win.
* The Red Death is the radioactive mass that is consuming the planet. A Safe Zone ring will appear on the map. Periodically this ring will shrink. Keep your units inside the ring to avoid the Red Death.
* On the top-left on the in-game screen is the Red Death tracker. The left portion tells the player how many turns until the ring shrinks, and the right-hand portion tells the player how much damage units will take if they end their turn inside the Red Death.
** Red Death damage increases as the game progresses.
** When the ring shrinks, the Red Death will advance each turn until it reaches the ring. This gives units caught outside of the ring some time to reach the safe zone.
** Units cannot heal in the Red Death.
* You can gain new units and supplies in the following ways:
** Find and clear City Ruins to gain equipment. These appear as war-torn cities with stacks of crates and flares around them. A Ruined City can grant experience points, an Infantry, a Machine Gunner, an AT crew, or another Civilian.
** Clearing a Raider Camp grants either a Helicopter Gunship, an AT Crew, or a Thermonuclear device (once you receive one, any of your combat units can use it).
** Once the “Red Death” ring starts to advance, Supply Drops can appear near the ring edge (also has a notification so you can find them). These lucrative drops can grant either a Tank, a Mobile Artillery, or a Thermonuclear device.
* Oceans and Lakes are corrosive and will damage your units each turn as you cross, so be quick!
* Global heal rate increased from normal for fast-paced gameplay.
* Units have unique promotion trees. Promoting units heals only 25 HP.
* Raiders are random opponents that wander the map, making opportunity attacks on players from their camps. Raider units take no damage from the Red Death.
* A typical match will take anywhere from 15 to 50 minutes depending on the number of players, and skill of play.

==AI==
===Domination===
* Improve ability to use GDR's (or other mixed melee/range) to take cities.
* All expansions: Allow units to move out of threatened areas when endangered, even on neutral territory. This manifested in AI units staying still and fortified while being attacked by ranged or air until they were dead.

==Performances==

* All expansions: Perf optimizations to both Shaka and Mansa Musa.
* All expansions: Reduced memory usage.
* All expansions: Additional graphics performance improvements.
==Bugs==
===Production Overflow===
* Add the concept of 'salvage' production to the Build Queue. Previously, when salvaging production from a lost Wonder build, the production was added directly back to the build queue. This caused problems of not knowing where the extra overflow came from as well as causing build production to happen when the player's turn was not active.
* e. Player A and B are making the same Wonder. Player A takes their turn, then Player B takes their turn and finishes the Wonder. The salvage production would be added to Player A's build queue immediately, possibly causing something to complete if the player had multiple things in their build queue.
* Now, when the salvage production is given to player A, it is stored and then applied to player A's production overflow when player A becomes turn active again. This also fixes the issue of losing legitimate overflow, where we force clear production overflow on turn end to prevent a user from 'banking' overflow by force-ending their turn when a city has no production.
* Fixed an issue where production on a unit could be transferred to something else by removing that unit from the production queue.
===UI===
* When purchasing something in a city, make sure that if it was already in the build queue, it goes through the motions of removing the item in the build queue as if it were complete, so that if it was the first item, the next item in the build queue starts building properly.
* The user was able to open but was unable to close the World Congress screen while the game is paused in multiplayer.
* Fixed multiple Gossip reports issues.
* Fix usable scroll area and logo clipping for various resolutions.
* Remove the rank border designating a score tier while participating in a non-scored Emergency during gameplay.
* A misleading "Location Pin" icon was present for Projects, Competitions, and Emergencies when the player views the Active Effects menu in the World Congress.
* The “previous results” icon was appearing in low resolution when voting on a Resolution that has appeared before in the World Congress.
* The target civ icon was appearing low resolution when viewing a Military Emergency.
* The Alliance Points appeared with a zero denominator when viewed after an Alliance expires during expansion gameplay.
* Climate Screen - Use the territory name as a fallback for continent name for climate events which will usually give us names for bodies of water.
* Production/Gold/Faith production buttons will now be highlighted properly based on which production panel is currently selected.
===Gameplay===
* Fixed a bug where pillaged districts in a conquered city would cost the full production price to repair. Now they cost 25% as intended.
* Fixed a bug where pillaged districts would not regain applied bonuses upon repair.
* Changed Mapuche's Toqui experience bonus ability to be permanent on units so that it remains even after the governor is removed from the city.
* Pillaged dams no longer prevent flooding.

* Apply FOW blending in river overlay pass.
* the game camera on the Ski Resort will now shake the snow. Why? Just ‘cuz.
* Adjusted volcano visuals to feel more volumetric and rolling/boiling.
==All expansions: World Builder==
* Added first pass at hand-drawn river flooding.
* Edge case notes:
** Only works for floodplains at least 3-long.
** Only works for hand-created maps, not adjusted map-script created maps.
** There are a couple places where a user may place a floodplain where it will never flood (like haring a plain with another river branch, for example).

* Don't show spurious "Wonder" district in Player Editor anymore.
* Add labels to all the items in the General tab of the player editor.

* Delete units when a player is edited.
* Fix case where capital city would have no name if you changed a civ's leader to not match (Should help with mod civs too).

===Tiled Map Importer===
* Fix additional crashes seen in the wild when importing maps from Tiled editor.
===Misc===
* All expansions: Removed constraint on map start positions that only allowed 1 entry for map/plot, as it was too restrictive for modders.
