Release 1.0.3 Notes, 5/10/2018

[WINDOWS] [STEAM] [GOG] Added an optional BATTLETECH Launcher that can be used to configure the following options before launching the game: Borderless Windowed Mode, Exclusive Fullscreen Mode, Video Rendering API. We recommend using these options for troubleshooting if you are experiencing hardware or software compatibility issues. To use this launcher, run the BattleTechLauncher.exe in your installation folder. In GOG Galaxy, you can open the More menu next to the Play button and choose Other -> Configure BATTLETECH.

[STEAM] Added a warning popup that appears if the Steam API fails to initialize on game start.

Added text to the video settings screen to indicate that some settings will not be applied until the next game load.

Added an option in video settings menu to show unsupported display resolutions (defaults to off).

[macOS] Support for non-standard Steam install directories (directory paths with special characters like "=" in them.)

Fixed some hitches when destroying units and buildings during combat.

Memory management improvements around 'Mech destruction.

Fixed an issue that could cause MechWarriors to become permanently stuck in the High Spirits or Low Spirits state.

Fixed an issue where saving the game immediately after salvaging enough parts to complete a new 'Mech could cause that new 'Mech to disappear upon reloading that save game.

Fixed an issue that could cause allied units in Escort missions to fail to move into the extraction zone under certain circumstances.

Fixed an issue where choosing to store a 'Mech with an active work order, then cancelling the warning popup, would cause the screen to become unresponsive.

Fixed a few issues with starting location spawn points on procedural missions.

Fixed hair shader to better support brighter colors in character creation, tweaked some hair and beard textures, and added some brighter color swatches.

Added new portrait presets and customization options.

Fixed an issue that prevented completion of the "Rock 'Em" and "Sock 'Em" achievements.

Fixed an issue that could prevent completion of the "Complete Roster" achievement.

Fixed an issue that trivialized completion of the "Laser Show", "Bullet Farmer", and "Raining Fire" achievements.

Fixed artifacting issues present on a subset of "Mercenary MechWarrior" custom Backer Emblem rewards.

Made the Backer Atlas "SBA" prefab available for the Atlas II-HT (in addition to being available for the standard Atlas AS7-D.) Made the Shadow Hawk "Umbra" prefab available for the Shadow Hawk 2H. Made "Valhalla" prefabs available for their respective chassis variants.

[SKIRMISH] Alternate prefab 'Mechs are now considered stock, and display in the Stock 'Mechs list in Skirmish Lance Config.

[SKIRMISH] Copying an alternate prefab 'Mech now correctly preserves the 'Mechs variant appearance.


IMPORTANT: If you switch to the public_beta branch, please note that when playing Multiplayer Skirmish, you will only be able to play against other players on the public_beta branch. The Lobby browser does not currently denote which players are on the public_beta branch and which are not (but will in future releases.) If you switch to the public_beta branch and then want to create a multiplayer lobby, please add [BETA] to the front of your Lobby name.



How to switch to the public_beta branch (GOG):

Within the GOG Galaxy App, Navigate to your library.

When you hover over the BattleTech library entry, find the small menu expansion arrow in the bottom right corner of the BattleTech App - select “Settings”

Click Beta Channels on the right side of the header and select “On”

Click the Channel dropdown and select “public_beta”

Dang. I am just now completing download of 1.0.2.

There also seem to be some new customization options for the main character. Besides the new, brighter hair colours, there's several new hairstyles and beard options, along with some extra makeup options I can't remember seeing on release.

Changelog for Patch 1.0.4 (added 22 May 2018):

* Fixed an issue introduced in Release 1.0.3 where the campaign timeline could stop advancing under certain circumstances - most commonly, after the death of one or more MechWarriors with active temporary tags (e.g High Spirits) on them.

elease 1.1.1 Notes, 6/27/2018

Fixed an issue where the starter MechWarriors (Glitch, Behemoth, Dekker, Medusa) could occasionally also appear as hireable Ronin MechWarriors in hiring halls later in the game.

Fixed a bug that could cause tooltips to fail to spawn in the Store under certain conditions.

Fixed an issue where tooltips could sometimes appear truncated at the bottom.

Fixed an issue where users could be unable to use Lance Configuration via the Multiplayer Skirmish Lobby if they had not yet played the campaign or single-player skirmish since updating to BATTLETECH version 1.1.

Fixed an issue where loading a save game generated in the Axylus priority mission, right after securing the crash site, could result in a progression blocker.

Fixed a bug that was causing attacks to hit 'Mech head locations more frequently than intended.

I'm no complainer, but thank you HBS. :)

An important fix. Glad it`s sorted.

Changelog for Patch 1.1.2 (added 26 July 2018):

* Fixed a race condition that could cause a softlock after flamer attacks made with the Firestarter 'Mech.
* Fixed an issue where the Capture the Argo mission on Axylus would fail to progress after loading a save game created right after securing the Argo crash site, but prior to new enemy units appearing.
* Fixed an issue where players could use the navigation starmap to accept travel contracts they did not meet the reputation requirements for.

Changelog for Update 1.3.0 (added 27 November 2018):

New Free Features & Content
* All-new Career Mode - Career Mode challenges you to begin the game with the Argo in a random system, with a random group of MechWarriors, with no story missions to rely on for big payouts. Wander the Periphery taking contracts (and Flashpoints, if you own Flashpoint!) and manage and grow your mercenary company to earn a final score. Career mode is played in Ironman mode by default, so it is also possible to “lose” this mode unrecoverably. (But Ironman mode can be disabled, and all the same granular difficulty settings from the campaign can also be adjusted in Career Mode.)
* Revamped MechWarrior abilities - We heard a bunch of feedback about the Bulwark ability and how you HAD to take it to finish the campaign and it got us thinking… and then revising Bulwark… and realizing that we should just rebalance the whole dang set of abilities. Then we put it out as an opt-in Beta and got some great feedback - thanks! We’ve been working on it ever since and we’ve released the revised abilities in 1.3. You can read the complete details in this forum post[forum.paradoxplaza.com]. The first time you load any game session after updating to 1.3, you'll see a popup informing you that all of your MechWarrior skills have been refunded, so that you can review the new abilities and respec accordingly.
* Revisions to the Reputation System - We’ve increased the rate at which reputation rises and falls so you can really feel the effects of your actions. When you reach the maximum possible reputation with a faction, you become eligible for an Alliance. By entering into an Alliance, you mark yourself an ally of that faction - and an enemy of that faction's enemies.
* Faction stores - In addition to making higher difficulty contracts and salvage available, Alliances also allow you to access faction-specific stores containing items you might not find anywhere else.
* Black Market stores - If you play your cards right, criminal elements will allow you to buy access to the Black Market, where you’ll find some equipment that fell off a transport…
* New Events, including cameos from two Legendary MechWarriors (these were part of our “social sharing” Backer reward from the Kickstarter, and we expect the other two cameos to make it into the next free update.)
* New mercenary contracts - now you can take jobs from Pirates!
* New inventory items - including rare LosTech from before the fall of the Star League!
* New Achievements - 19 new mercenary and story achievements have been added to the campaign and career modes!

Improvements
* Increased the number of possible encounter types on existing maps for more variety.
* Star Map updates for new Stores and the Black Market
* New space travel animations added
* New camera angles added in group conversations
* Players can now move 'Mechs from one Mech Bay slot to another. Organize away!

UI
* Many added, updated, and fixed Tooltips
* Priority items now remain visible on the salvage list after confirming their selection
* Fixed the broken Settings toggle for auto-selecting units outside of combat
* Fixed an issue which would cause the portrait and description on the “Arrived at Destination” popup message to occasionally be cut off
* Fixed an issue which caused Reputation indicators to be partially cut off on the Negotiation screen
* Removed Reputation status icons for Locals’ (and certain other factions you cannot gain or lose Reputation with) from Stores and AAR. This will keep Reputation focused on the Factions that matter.
* Fixed an issue which caused the pattern selector in the Mech Bay to stop responding after switching patterns too rapidly
* Fixed an issue which caused the 'No existing save games' prompt to display after quitting from the 'Load Game' menu evoked after running out of C-bills
* Made the Settings Menu able to be dismissed using the ESC key
* Fixed the Morale tooltip to not always show '0' value for the Current Morale
* Fixed an issue which caused the background behind the Leopard to change when navigating between screens
* Fixed an issue which could cause the 'Load Save' button on the Out of Funds pop-up not respond for the user's input
* Fixed UI visual anomalies which could occur after using the Pattern selector or the Refit menu in the Mech Bay
* Items in 'Store' and 'Storage' menus are now sorted more by types
* Various small UI and messaging improvements

Accounts
* Special characters are now allowed in account creation passwords (!@#$%^&**()_-=+[]<>)

Bugfixes
* Fixed multiple spawn spots on maps where ‘Mechs would get stuck
* Collision improvements to existing maps
* Fixed a soft lock players could occasionally encounter after commanding fire at the first test dummy ‘Mech in the campaign tutorial
* Fixed an exploit where the player can perform Called Shot on ‘Mechs that are not knocked down by using the keyboard
* Fixed an issue in Character Creation which caused the last screen of 'Your Background' to be missing its background image after returning from the 'Your Appearance' tab
* Fixed an issue which caused the 'Sprint' skill to not be toggled for the next selected Mech if the user attempted to use it on an unstable Mech
* Fixed an issue which caused Player 2/Guest UI to be missing Heraldry Image in Lobby & Combat UI
* Fixed a lighting issue on OSX for some graphics cards. For more info, see: https://forum.paradoxplaza.com/forum/index.php?threads/battletech-update-1-2-mech-lighting-graphical-issues.1116636/
* Fixed an issue which enabled users to join the lobby of a multiplayer match that was completed
* Fixed a save/load issue which caused overheated ‘Mechs to appear in their shutdown pose after loading a combat save
* Fixed a save/load issue which caused increased map lightning in particular biomes after loading a combat save
* Various small graphical bug fixes on existing maps
* Fixed an issue in the Liberation of Weldry mission that caused you to remain in interleaved turn mode after all your first set of enemies were defeated.
* VFX improvements on some weapons!
* Fixed an issue in the Mech Bay which could cause Filters to be reverted to the default state after deleting a custom 'Mech
* Collision and pathing improvements to certain maps
* Improvements to beacons and objective communication
* Many additional small improvements and bug fixes

Known Issues (to be hotfixed asap)
* Flashpoint owners cannot currently play multiplayer games against non-Flashpoint owners.
* Turret generator destruction can distort audio in Target Acquisition missions. Restarting the title fixes this.
* Skirmish Mech Bay - Deleting any customized 'Mech causes a 'Mech from the custom list to duplicate. This is a visual-only problem and is resolved on re-launch of the game.

Moved my comment to a distinct new thread here now i saw i wasnt the only one being puzzled by some contradiction in patch 1.3 changelog

so the changelog thread is kept clean

While i totally agree that this is a contradictory "solution" and a bad re-working of the skills (now Bulwark is even more mandatory than before, at least in half your pilots if not all given how it works now) i do think this would make a good new thread for discussion and does not belong here, imho. I like changelog threads to be as clean as possible to quickly look at all the changes from patch to patch (or even looking at previous patches in case a game is updated->balanced in the wrong way or has some new bugs or worse optimization, like i am reading 1.3 has) If you finally move your comment to another thread, can a mod move my answer also there, please? Thank you in advance! (i mean, moved or deleted to not be here alone without any reason)
