Dear Alchemists,

v0.4.3.4131 is now live! We’ve added some new things to this version, such as retractable beam, conveyor passage and hangable conveyor bridge. We’ve also optimized the device buffer and fixed several bugs. Please check the update log below for details.

v0.4.3.4131 Update Log:

New items:

Added a new hangable conveyor bridge that can be adjusted in height by dragging.

Added a retractable beam and a retractable conveyor passage, both adjustable in length by dragging.

Added two new metal stand variants.

Device buffer optimization:

When items input via conveyor belts, advanced crafting devices will now only buffer up to twice the amount of materials required by the recipe.

Furnaces and nurseries will only buffer fuel/fertilizer up to twice their slot count.

Manually added items are not affected by this change.

Bug fixes & adjustments:

Fixed an issue where item transfer speed was incorrect when devices were directly connected to each other.

Fixed an issue where customers would occasionally spawn inside player's shop.

Fixed an issue in multiplayer where build options in the hotbar would disappear after a client rejoined the game.

Fixed an issue where blueprints in the hotbar could be overwritten by newly unlocked tech.

Fixed an issue where Mercury would not appear in random quests.

Fixed a potential crash issue.

Temporary item bags are no longer generated in Sandbox Mode.

Advanced customers now spawn correctly in Sandbox Mode.

Adjusted the building cost of the Cauldron: 30 Bronze Ingots → 20.
