What happened?

Bots will not heal afflictions no matter the Treatmentthreshold IF THOSE AFFLICTIONS DO NOT LOWER VITALITY.
Vitality threshold to trigger AI healing is defined at a hard 75/90

Barotrauma/Barotrauma/BarotraumaShared/SharedSource/Characters/AI/Objectives/AIObjectiveRescueAll.cs

Lines 18 to 19 in fd34473

	private const float vitalityThreshold = 75;
	private const float vitalityThresholdForOrders = 90;

A bot could be affected by the nastiest debuff there is and not try to heal it because it doesn't correspond to one of these THREE HARDCODED AFFLICTIONS TYPES:

Barotrauma/Barotrauma/BarotraumaShared/SharedSource/Characters/AI/Objectives/AIObjectiveRescueAll.cs

Lines 90 to 115 in fd34473

	public static float GetVitalityFactor(Character character)
	{
	float vitality = 100;
	vitality -= character.Bleeding * 2;
	vitality += Math.Min(character.Oxygen, 0);
	foreach (Affliction affliction in GetTreatableAfflictions(character, ignoreTreatmentThreshold: true))
	{
	float strength = character.CharacterHealth.GetPredictedStrength(affliction, predictFutureDuration: 10.0f);
	vitality -= affliction.GetVitalityDecrease(character.CharacterHealth, strength) / character.MaxVitality * 100;
	if (affliction.Strength > affliction.Prefab.TreatmentThreshold)
	{
	if (affliction.Prefab.AfflictionType == AfflictionPrefab.ParalysisType)
	{
	vitality -= affliction.Strength;
	}
	else if (affliction.Prefab.AfflictionType == AfflictionPrefab.PoisonType)
	{
	vitality -= affliction.Strength;
	}
	else if (affliction.Prefab == AfflictionPrefab.HuskInfection)
	{
	vitality -= affliction.Strength;
	}
	}
	}
	return Math.Clamp(vitality, 0, 100);

Bots will not try to heal hunger even past the threshold

Version

v1.9.7.0 (Summer Update 2025)

[Regalis11]

This has now been addressed in our private repo: there's a new setting called VitalityLossRequiredForTreatment to Affliction:

VitalityLossRequiredForTreatment
Does the affliction need to have caused some amount of vitality loss for bots to consider treating it? Normally bots use vitality loss as a way to determine what kind of injuries need treatment, but some afflictions (e.g. poisons, infections) might require treatment regardless of the vitality loss. If disabled, the bots will use the strength of the affliction to evaluate the severity instead of the vitality loss. Defaults to true for all afflictions that aren't of the type Paralysis, Poison or HuskInfection.

Changes coming up in the next unstable build and the upcoming Winter Update.
