Major update

v0.9.78 - Better Machine Filtering & Faster Item Selection

All newsPlayers around this dateRead on Steam

Hi miners, 😄

Thank you very much for your continued support, reports, feedback, and suggestions.

This update focuses on improving machine management and item selection, especially as mining operations continue to grow across multiple areas.

Machine Management now includes additional filters and automatic list updates, while keyboard players can directly select Hand Slots using number keys. We have also fixed an issue that could cause carried boxes to fall into the world after reloading a save within the same session.

Here is what is available in the latest version.


Main Updates

1. Machine Management Filters & Live Updates

Machine Management now includes additional filtering options and automatically reflects changes made to machines in the world.

a. Machine Level Filter

A new Machine Level filter allows players to display machines based on their current upgrade level.

Available options include:

  • All

  • Level 1

  • Level 2

  • Up to Available Level for Machines

This can be useful when checking or managing machines at a specific upgrade level.

b. Location Filter

Machines can now also be filtered based on their current Cave Area:

  • Cave Area 1

  • Cave Area 2

  • Cave Area 3

This provides a clearer way to review machines located in different parts of the mining facility.

c. Automatic Machine List Updates

The Machine Management list now updates automatically when machines are:

  • Deployed

  • Repacked

  • Sold

Machines will immediately appear or disappear from the list based on their current state, without requiring a manual refresh.

2. Number Hotkeys for Hand Slots

Keyboard players can now directly select Hand Slots using the number keys:

  • 1–9 select Hand Slots 1–9

  • 0 selects Hand Slot 10

Slot numbers are displayed directly on occupied hotbar slots so the corresponding shortcut is easier to identify.

The number indicators are hidden on empty slots and while using a gamepad.

Number hotkeys are temporarily disabled during machine or rack placement so they do not interfere with consecutive placement controls.


Bug Fixes

1. Boxes No Longer Drop from Hand After Reloading

Fixed an issue where boxes stored in the player's Hand Slots could fall into the world after returning to the Main Menu and loading a save again within the same game session.

This could also cause the number of boxes shown in the Hand Slots to decrease after reloading.

Hand Slot contents should now remain correctly restored across repeated save loading within the same session.

2. Fix Employees Using the Smallest Stairs

Fixed an issue where employees could not properly navigate through the smallest stair size.

Employees should now be able to pass through and use these stairs correctly when moving between levels.


Thank you again for your continued support, reports, and feedback.

We will continue improving management tools and quality-of-life features based on your reports and suggestions.

If you encounter any issues or unexpected behavior, please report them through the in-game report feature or through the Steam Discussions page so we can investigate further.

See you in the next update!
