Core Keeper 1.2.1.2 - Stability Patch Notes (7th May 2026)
Core Keeper's second hotfix in two days lands with exploit fixes, a Master volume slider, and a batch of bug squashes.
Two days after 1.2.1.0 dropped with Casual mode and chest labels, Pugstorm is back with another small but useful patch. 1.2.1.2 is live today, billed as a stability update, and it earns that label.
The most notable gameplay fix closes an exploit where players could fire the Titan Breath indefinitely by holding both attack buttons at once, bypassing mana costs entirely. That's the sort of thing that quietly warps multiplayer balance, so getting it patched quickly is the right call. On the quality-of-life side, circuits, conveyor belts, drills, and several other placeable objects now regenerate health over time, bringing them in line with how other buildables already worked. There's also a new Master volume option in audio settings, which I'm surprised wasn't there before. Rounding out the fixes: sprinklers now keep soil watered when no players are nearby, Robot Arm filters work correctly with Fishing Nets and Critter Catchers, and Xbox Series players get a shader fix for The Shimmering Frontier biome looking washed out.
Nothing here reshapes the game, but it's a clean, focused patch. Everything in the update is listed below.
