Hello, friends!

Our March 2025 Quality of Life update is out today! This free update squashes some long-standing bugs and improves UX in all versions of the game. It also includes DLC-specific additions, bug fixes, and improvements for The Bionic Booster Pack. 

Highlights of this minor update include:

QoL & bugs for all versions
Weve introduced a smarter search function in the build menu and Research screen. It uses fuzzy search, synonym matching and even initialism—for example, you can now search "mm" to find the Microbe Musher—to help you find what youre looking for faster. Improving searchability is an ongoing process, and we hope to keep building this out in the future.

Another thing thats got us all in a fizz is the new range of visual effects applied to liquids: a mild "underwater"-type distortion becomes increasingly conspicuous as the liquids temperature rises, eventually leading to bubbles that intensify as it approaches its boiling point.  

Weve also changed the way that liquids get displaced in the sim, to fix some liquid duplication bugs. 

The database continues to expand, and now contains entries for our quirky little Duplicants—including basic health metrics and links to the various systems that keep the crew alive and well. 

The Bionic Booster Pack
We fixed a bug where the Flydo fetch drone would fly erratically on autopilot when it depleted its power bank supply. We also updated the Skill screen for Bionic Duplicants to add an overview of all the boosters available on that world. You can even assign or unassign boosters directly from that screen. Bionic Duplicants are now susceptible to diseases, too! 

The Frosty Planet Pack
Bammoths wont run into walls anymore, and there are now themed Monument blueprints for this DLC in the Supply Closet! 

Summary
We fixed a bunch of bugs (including some veteran ones like liquid duplication!), made our search functions more responsive, added visual feedback to liquids that are heating up, improved booster management in The Bionic Booster Pack, and added cosmetic blueprints to The Frosty Planet Pack. 

If your mods are breaking or you need a little extra time before switching over, you can opt in to the temporary, unsupported Previous Update branch.
