   • ≈🎯BehaviorOxygen Refillrefill threshold—→Breathable

     Bionic Duplicants will now refill oxygen tanks during scheduled downtime in cells that meet the 'Breathable' threshold.

     quality

   • ≈🎯BehaviorOxygen Refillcritical refill triggerlow→empty

     Critical/involuntary tank refilling now only triggers when the oxygen tank is completely empty.

     neutral

   • ≈🎨VisualOxygen Refillanimation—→Added

     Bionic Duplicants now play the 'Gasping for air' animation after refilling from an empty tank.

     visual

   • ≈🎯BehaviorOxygen Refilldecision frequencyhigh→low

     Reduced how often Bionic Duplicants reconsider their options when selecting the best cell to refill from.

     performance

   • ≈🔁ReworkSuffocationbreath recoveryunique→Standard

     Aligned suffocation breath recovery with Standard Duplicants for a more consistent 'near death' experience.

     neutral

   • ≈🎯BehaviorOxygen Refillpositioningstacking→avoiding

     Bionic Duplicants will now try to avoid stacking on top of each other when selecting refill locations.

   • ≈🛠QoLRescuepriority visibilityAlways→Powerless only

     The rescue priority setting now only appears when Bionic Duplicants are Powerless, reducing UI clutter.

   • ▲🐛Bug fixstability

     Fixed crashes occurring when Bionic Duplicants were critically low on oxygen or during red alerts.

   • ≈🐛Bug fixalert effectPersistent→Corrected

     Fixed a bug where the yellow alert screen effect persisted in rockets based on a Powerless Bionic Duplicant's rescue priority.

   • ▲📊NumericOxygen Refillinhale radius—→Increased

     Increased the radius for inhaling oxygen when refilling internal tanks, making it easier for Bionics to breathe.

     Improved refill range

   • ▲📊NumericCritical Breathingconsumption throughput—→Standardized

     Bionic Duplicants now have a guaranteed minimum oxygen consumption throughput during critical chores, matching standard Duplicant recovery behavior.

     Guaranteed minimum throughput

   • ▲🎯BehaviorOxygen Searchpathing logic

     Improved oxygen search behavior to better balance travel distance, cell safety, and oxygen mass for more efficient location selection.

     Better location selection

   • ≈🛠QoLOxygen RefillUI feedback—→Added

     Added a specific status item and tooltip for Bionics urgently refilling depleted tanks to clarify they will use the nearest breathable area.

     New status item

   • ▲🐛Bug fixAtmo SuitCO2 productionProduced CO2→None

     Fixed a bug where Bionic Duplicants would produce CO2 upon unequipping an atmo suit.

     Bugfix

   • ≈🐛Bug fixCommand Moduleassignment statusIneligible→Assigned

     Fixed an issue where Bionics inside the Command Module were incorrectly shown as ineligible instead of assigned.

     UI fix

4. Dec 17, 2024·[Game Hotfix] - 647408+5

   • ▲🐛Bug fixsurvival

     Bionic Duplicants can no longer suffocate to death while actively absorbing oxygen canisters.

     bugfix

     Fixed an issue where Bionic Duplicants would become invisible during the Shocker stress response.

     bugfix

   • ▲🐛Bug fixShocker stress responsestate

     Fixed an issue where Bionic Duplicants would freeze when surrounded by water during the Shocker stress response.

     bugfix

   • ▲🎯BehaviorOxygen Tank Consumptiontask priority

     Fixed a bug where Bionic Duplicants would drop the task of consuming an oxygen tank to absorb from the atmosphere instead.

     bugfix

   • ▲🎯BehaviorTransit Tube Travelmovementstop in tube→stop after exit

     Bionic Duplicants who run out of power in a transit tube will now complete their travel and stop after exiting, rather than stopping inside the tube.

     behavior

   • ▲🐛Bug fixMedical Cotusage

     Fixed a bug where Bionic Duplicants were not utilizing medical cots during their sleep schedule blocks.
