Small Supplementary Update: Electronic Module System and Stability Fixes

Dear Conductors,

This update introduces the brand-new Electronic Module System . You can install Speed, Production, Energy-Saving, Silent, Power Generation, and Capacity Modules in compatible electrical devices, upgrading your equipment to suit the direction of your train's development.

We have also adjusted King Fish spawn chances and related tips, fixed issues involving acid rain, Oxygen Boxes, respawning after falling into lava, and map loading, and reduced the cost of obtaining certain technologies and fishing items.

Here are the full details of this update.

New Electronic Module System

You can now install electronic modules in supported electrical devices to improve machine performance according to your needs.

This update adds six types of electronic modules:

**Speed Module:** Slightly increases operating speed. Effects stack. For electrical devices only. **Production Module:** Slightly increases the quantity of items produced. Effects stack. For electrical devices only. **Energy-Saving Module:** Slightly reduces the electricity required to operate. Effects stack. For electrical devices only. **Silent Module:** Completely eliminates operating noise. For electrical devices only. **Power Generation Module:** Increases electricity output. For power-generating equipment only. **Capacity Module:** Adds internal item slots. For electrical devices with storage slots only.

Installing Modules

When you approach a device that supports modules:

Press F to open the module panel Press E to use the device's original interaction

The top of the module panel shows which module types the device supports. Gray module icons indicate empty slots with no module installed.

To install a module, you can:

Drag the module into an empty slot Use Shift + left-click to quickly install one module Drag a module in using the left, right, or middle mouse button

To replace a module, first click or drag the existing module out, then insert a new one.

Different devices have different numbers of module slots. For example, solar panels currently have 1 module slot . Check the device panel for supported types and the number of slots before installing modules.

Before dismantling a device, retrieve any electronic modules installed in it.

King Fish System Adjustments

We have readjusted how rain and King Fish Lures affect King Fish spawn chances.

Changes:

The King Fish spawn multiplier in rainy weather has changed from 5× to 3× The King Fish Lure multiplier has increased from 2× to 3× Updated the King Fish Lure description accordingly Updated the rainy-weather fishing tips accordingly

In the current version, King Fish can appear in any body of water.

The Magician character still slightly increases the chance of hooking a King Fish.

Conditions

Chance of Hooking a King Fish

Normal weather

0.571%

Rain

1.714%

Normal weather + King Fish Lure

1.714%

Rain + King Fish Lure

5.143%

Mixed Bait Price Adjustment

The base shop price of Professional Mixed Bait has been halved:

Old price: 10 Oxygen Coins New price: 5 Oxygen Coins

This makes it less costly to try out the bait system early in the game.

Map Table and Map Marker Fixes

Fixed incorrect translations in the Map Table's tips.

Added a world map icon for the map information board near the rainforest, making it easier to find and read the map information.

Lava Respawn Fix

Fixed an issue where characters continued taking lava damage after falling into lava and respawning, causing repeated deaths.

Respawning now correctly clears the previous lava damage state.

Advanced Oxygen Box Fixes

The Advanced Oxygen Box now supplies oxygen to the surrounding area only after it has been placed.

It no longer takes effect in the following states:

While holding the device in your hands During the red placement preview indicating an invalid position During the blue placement preview indicating a valid position While moving the device

Also fixed an issue where empty Oxygen Boxes still increased the oxygen concentration around them.

Only Oxygen Boxes with a usable oxygen reserve now supply oxygen to the surrounding area.

Technology Unlock Balance Adjustment

Reduced the materials required to unlock the blueprint for the tier 4 technology "Electric Lighting," bringing the cost more in line with its practical use and stage of progression.

Feeding Notification Improvements

Improved how notifications are displayed when another player feeds you.

Now:

A notification for a single feeding normally appears for 1.5 seconds When you are fed multiple times in succession, the current notification ends sooner Each queued notification appears for 0.5 seconds Once the queue has cleared, new notifications return to a duration of 1.5 seconds

This reduces the time notifications occupy the screen when you are fed repeatedly.
