Highlights

Fixed companions not spawning correctly at HQ after dismissing them.
Fixed disappearing Perks on companions after dismissing them.
Fixed inability to open doors in Ranger Citadel and Ag Center Central Complex after using Examine while playing with a controller.
Added Steam Controller support! Select Steam Controller from the Options menu to use it (Steam version only).

Known Issues

Some users may notice a memory leak while playing for longer periods of time. This is a known Unity engine bug and will be addressed in a hotfix in the near future.
Steam Controller support may not function correctly on some Windows 8, Mac or Linux systems. We are currently investigating this.

General

Fixed companions not spawning correctly at HQ after dismissing them.
Fixed disappearing Perks on companions after dismissing them.
Fixed inability to open doors in Ranger Citadel and Ag Center Central Complex after using Examine while playing with a controller.
Fixed a bug which could cause Precision Strikes with melee attacks to not apply correctly in certain conditions.
Fixed a bug with Rangers sometimes running in place when conversation or cutscene stopped them.
Fixed a bug where Ranger running animation could stutter when playing with a controller at low framerates.
Fixed a bug which could cause killed enemies to respawn if the player manually saved over and loaded the AutoSave slot.
Fixed a bug where saving the game was greyed out after fixing the robot arm in the Ag Center Central Basement.
Fixed a bug where resetting keybindings to defaults and then customizing them immediately after could result in corrupt keybindings after restarting the game.
User Interface
Export option has been re-added to Character Creation. Look for it on the final step for that specific character you want to export (Select Quirk).
Fixed a bug where male portrait snapshots weren't taking height of the character into account properly. Snapshots should now correctly show the character's face.
Fixed a bug where custom portraits would sometimes temporarily disappear from the portrait gallery.
Fixed a bug/exploit where Attribute points could be gained or lost permanently with certain status effects.
Fixed a bug which could sometimes prevent selecting certain skills in the Skills screen while playing with a controller.
Fixed a bug which could sometimes cause the Skills Radial menu to only show Lockpicking as a valid option while playing with a controller.
Fixed companion members showing conversation cursor while in the squad.

Audio

Fixed voice-over lines not playing in some conditions after returning to a location.
Conversation voice-over dialog now plays as 2D audio.
Bark voice-overs now play as 50/50 2D and 3D so they can be better heard at a distance.
Fixed Sniper Rifle reload sound on certain weapons.

Gameplay

Added Steam Controller support! Select Steam Controller from the Options menu to use it (Steam version only).
Fixed Meson Cannon not properly firing on the player.
Fixed Attack of Opportunity melee Perks from interfering with Ambush functionality.
Added some more Shovels to vendors throughout the game, just in case the player lost theirs.
Added missing Open tooltips to the Highpool Underground doors. Players were missing that the doors could now be opened simply by left-clicking on them.
Turned off Investigate Sounds property from the Rodia vendor guards near the gate. This was causing them to run around awkwardly if the player fired weapons nearby.
Lucky CON bonus on characters is now saved properly.
Fixed a bug where a cutscene sometimes wouldn't end in Temple of Titan the second time you visited Dr. Kyle.
Veteran characters are exported correctly on game end.
Veteran characters no longer get exported with missing clothes. They were being dealt a certain damage type in the endgame which also just happened to vaporize clothing.

Balance

Increased the effects of Manic Depressive to +2/-2 to Attributes, to make it a bit more compelling to select.
Reduced the effects of Disparnumerophobia to +1/-1 to Attributes.
Increased the Applied Force line of Perks slightly.
Increased time range for Animal Husbandry effects to take place.
Increased Tactical Positioning damage bonus slightly.
Increased the Whack-a-Mole bonus to Chance to Hit slightly.
Increased the Bomberman bonus to Area of Effect range slightly.
Increased the Long Arm bonus to Throw Distance range slightly.
Increased the Loose Change drop chance slightly.
Increased the bonus granted by Intimidating, Affable and Know-it-All, to make them more compelling to select.
Reduced the Improvised Explosives salvage chance slightly.
Removed Friendly Fire chance from Master Hunter entirely.
Fixed Bandit line of Perks to no longer affect Submachine Guns.
Increased the Bandit line of Perks bonus attack chance.
Opportunist now shows the correct bonus damage. The text was previously incorrect.
Increased the effective range of Opportunist bonus damage slightly.
Increased Big Game Hunter and Roboticist bonus damage.
Updated the Alarm Disarming line of Perks, Ghost and Quick Reflexes. Ghost is now placed at a lower skill requirement and Quick Reflexes now grants permanent bonus Evasion. This should make them more compelling to take.
Removed Conductive flag from Goat Hide Armor, since it's not made out of metal.
Improved some old unique weapons so that they are more worthwhile to use.
Removed an erroneous 1.2x Field Medic skill multiplier on Mysophobic. The flat bonus healing effects still remain as described.
