Probably Stolen furnace smelting, Powerbloc, and machine guide

Furnace smelting, ingots, and the Junk Processing Module

The Furnace melts down salvaged metal and junk into usable ingots—which are required both for crafting and for upgrading Animal Cage size and maximum durability (+20 durability per ingot upgrade). Installing the Junk Processing Module on the Furnace expands what you can refine, and Patch 48.3.12 fixed a bug where the Junk Processing Module secretly drew twice its displayed power consumption.

Before buying any machine or container from a merchant, take advantage of the Update 049 quality-of-life feature that lets you open and preview containers and machines prior to purchase so you can verify their grid footprint and slot layout.

Powerbloc adjacency charging and Powerline Hijack

Every powered machine—from the Furnace and Bottle Printer to the Vacuum Robot—requires either swappable batteries or overnight grid power. Placing a Powerbloc next to batteries and machines charges all adjacent units overnight, and Update 049 ensured the Powerbloc charges adjacent equipment on the very first night after power is enabled.

Once you purchase the Powerline Hijack upgrade, the daily power service toggle disappears from the End of Day UI and remains permanently active without billing you. You can also swap owned batteries instantly by dragging a charged battery directly onto a depleted one.

Cryptographic Desequencer and keycard crafting rules

For tech-focused shopkeepers using the Cryptographic Desequencer, you can swap desequencer crypto modules by dragging one owned module onto another. To prevent wasted materials, blank disposable keycards cannot be placed into the output slot, a used desequencer cannot be slotted into another desequencer's chip slot, and unused Supply/Science keycards and chips were removed from merchant pools until their corresponding supply crates are active.
