Thanks to everyone for your continuing feedback on the Emperor of the Fading Suns Enhanced!
This update prioritizes three areas:
[olist]Quality-of-life fixes you have told us will make a big difference for you;
[/*]Bug fixes (thankful to say that while there are a number of these, none were especially big); and
[/*]Improvements for the map editor and modding.
[/*][/olist]Quality-of-Life Improvements
Okay, you were right. These REALLY speed up gameplay just watchour most recent streams!
New Message Window
This was easily one of the most-requested QoL changes. At the start of your turn you will see a new Messages dialog, with all the messages on one screen, You can exit out of these and never have to respond to most of them.
This means that you no longer receive a lot of building prompts at the start of a turn. Instead, you get a list and can resolve each city at your convenience, either through this new message screen or by visiting the city itself. Cities default to No Production if you do not give them anything new to produce.
Note that while you still need to respond to diplomatic entreaties (especially threats of war), we added a setting to the EFS.ini file so you can turn this feature off for most diplomatic requests.
We are aware of a graphic glitch that puts lines under the message (and other text) when you play at 1366 x 768 resolution. We hope you do not find this a problem, but we are looking into it.
No More Build Confirmation
This in itself shaves a lot of time off turns, especially later in the game. EFSe no longer asks for confirmation when starting unit production, or when building nothing. The prompt still appears if you change production from one unit to another to ensure you do not inadvertently waste resources.
More QoL
Added support for razing roads the Build Road command now razes instead if a road is already there. Neither costs movement
[/*]Added health penalty tooltips
[/*]Transports can now also be loaded by dragging the unit to another unit already in the transport and not requiring you take the unit off the transport first
[/*]Fixed some inconsistencies with unloading transports
[/*]Fixed Select All functionality when the current selection is sentried,
[/*]Added clergy counts to cathedral descriptions
[/*]The AI now correctly follows the 20 unit stack limitation
[/*]Bug Fixes
What bugs? We are just changing unintended functionality to intendedOkay, we admit they were bugs
Ministry Unit Confusion
This update addresses a few cases of the players own units intermingling with ministry units under player control (a so-called mixed stack), which caused a number of issues both technical and design-wise:
Fixed a bug where units captured using ministry units would be assigned to the players House.
[/*]Fixed a bug where claiming the reward from a cleared ruin using ministry units would create a mixed stack. The reward is assigned to the players own House. The ministry unit used to claim it remains outside. An exception to this is when defending spaceships capitulate in the ruin tile. To avoid a mixed stack situation, moving a ministry unit in to claim the reward will also place it under ministry control. Move ministry units out first to keep it for yourself!
[/*]Fixed buying from an Agora could place House resources among ministry units. Purchased resources will be given to the players House if there is room to do so without creating a mixed stack. Purchased resources will be placed under the control of the players ministry if only ministry cities and units have room. These resources can be used to produce either house or ministry units,but will be lost if the ministry changes owners!
[/*]Fixed Naval Transports not understanding House and ministry boundaries when loading and unloading units.
[/*]Fixed ministry cities overflowing their production into a tile occupied by units from the players house.
[/*]Fixed some problems with assigning ministries
[/*]Fixed all ministries having to share the same 20 units limit in space. Now each ministry can now bring a full 20 units without hindering the others.
[/*]\nLab/Research Fixes
Fixed research progression loss when assigning an additional lab.
[/*]Fixed lost lab research overflow after selecting Nothing.
[/*]Fixed out of control inactive labs count in the research window.
[/*]Fixed some problems with research point calculations
[/*]General Bug Fixes
Fixed crashes when disbanding units from the Group Finder
[/*]Fixed a rare crash when embarking unit into adjacent transports could crash the game
[/*]Fixed a hung game if a ministers House is eliminated in the same turn the Ministry is assigned.
[/*]Fixed a bug where interrupting a units movement with the spacebar would teleport the next unit moved.
[/*]Fixed when Space, Jump or Lander move types couldnt exit a transport on a river tile.
[/*]Fixed Zero-movement units being able to board transports
[/*]New units are no longer built on top of ruins if theres no free space in the actual city
[/*]Fixed problems with splitting some cargo types
