Fixes

Fixed the malevolent Mining Accident colonization event choice (it was giving +50% growth instead of -50%)

Fixed a bad adjacency bonus on the Preparedness Center (it was giving +95% resistance for each level!?!)

Fixed a crash if you hover over an out-of-bounds tile while using the teleport cheat

Fixed the "Win the Campaign" cheat

Fixed an issue causing ships to go off the screen in the battle viewer

Upgraded the version of Miles (the sound system) to fix sound issues and memory leaks

Many multiplayer fixes around lobbies and restored sessions

Fixed an issue where multiple simultaneous invasions would show the wrong info in the results window

Fixed a crash when attacking a planet with two fleets in the same action

Fixed a crash if a transport tried to invade a planet at the same time that it was joining a fleet

Fixed a crash if you fought 2 battles against one defender with spawned fighters and canceled the first battle in the same turn

Fixed an issue that would cause you to not be given ships by ideological events and anomalies if you obsoleted those ship designs in your ship lists

Fixed an issue where the planet keeps spinning in the battle viewer even if the simulation is paused

Fixed an issue where the old minimap border stuck around if you started a game within a game (only noticeable if you changed map sizes between those 2 games)

Fixed lots of typos

Didn't add any new typos!

Fixed an issue with ridiculously wide monitors (we were scoffing at the 3000 x 1080 resolution until we got a monitor to test it on, it looks pretty awesome)

Fixed an issue where you could build infinite resource requiring ships by using continuously build (When a ship is set to continuously build in a shipyard, and it requires a specific resource, it now checks if the player has enough of that resource before building. If not, it gets removed from the shipyard's queue and sends an Alert/Notification to the player to let them know)

Fixed a crash when going from the campaign to a multiplayer game

Fixed a stuck turn when the AI invades 2 planets at the same time

Fixed weekly treaty income not showing up in the production sub window

Fixed an issue allowing the player to get peace with the AI in scenarios (like the campaign) where peace isn't allowed

Fixed the jitterbug (AKA ships no longer wiggle when moving on large maps)

Fixed the Kinetic Accelerator to correctly boost the range of Kinetic weapons

Fixed the Quantum Leap ideological trait (it wasn't applying its +5 research per colony bonus)

Fixed the missing icon for Barrier System Focus

Fixed an issue allowing Food Distribution to be buildable while Xeno Irrigation was already built

Fixed the High Output Mining techs

Fixed the prereqs on the Biomass Resequencer

Fixed an issue where decay wasn't being applied for synthetic life. Decay is the process where population shrinks if you have more people than your population cap supports.

Fixed an issue where if a players faction power got high enough it would overrun and flip to 0, causing the AI to surrender

Fixed an issue where lobbies were only looking within your region for other players (now they look globally)

Balance

AI

General AI strategy improvements

Reduced bonuses given to the AI due to the AI being smarter

Performance

Removed some release level debug

Major late game turn time improvement on large maps (from the AI calculating paths across the entire map for pirates)
