This also cause the mod(eg. "Animated Arms: Adaptive Combat") to be incompatible with vanilla diving suits in this regard. Take combatdivingsuit as an example, I recommend rewriting the code as follows for better compatibility: Before

<StatusEffect type="OnWearing" target="Character" OxygenAvailable="-100.0" UseHullOxygen="false" />
<StatusEffect type="OnWearing" target="Character" ObstructVisionAmount="0.25"  PressureProtection="5750.0" LowPassMultiplier="0.2" setvalue="true" disabledeltatime="true">
  <Sound file="Content/Items/Diving/DivingSuitLoop1.ogg" range="250" loop="true"/>
  <Sound file="Content/Items/Diving/DivingSuitLoop2.ogg" range="250" loop="true"/>
  <TriggerAnimation Type="Walk" FileName="HumanWalkDivingSuit" priority="1" ExpectedSpecies="Human" />
  <!-- high prio for run animation so e.g. affliction-based run animations won't make the character run faster -->
  <TriggerAnimation Type="Run" FileName="HumanRunDivingSuit" priority="10" ExpectedSpecies="Human" />
</StatusEffect>

After

<StatusEffect type="OnWearing" target="Character" OxygenAvailable="-100.0" UseHullOxygen="false" />
<StatusEffect type="OnWearing" target="Character" PressureProtection="5750.0" LowPassMultiplier="0.2" setvalue="true" disabledeltatime="true">
  <Sound file="Content/Items/Diving/DivingSuitLoop1.ogg" range="250" loop="true"/>
  <Sound file="Content/Items/Diving/DivingSuitLoop2.ogg" range="250" loop="true"/>
  <TriggerAnimation Type="Walk" FileName="HumanWalkDivingSuit" priority="1" ExpectedSpecies="Human" />
  <!-- high prio for run animation so e.g. affliction-based run animations won't make the character run faster -->
  <TriggerAnimation Type="Run" FileName="HumanRunDivingSuit" priority="10" ExpectedSpecies="Human" />
</StatusEffect>
<StatusEffect type="OnWearing" target="Character" ObstructVisionAmount="0.25" setvalue="true">
  <Conditional ObstructVisionAmount="lt 0.25" />
</StatusEffect>

Reproduction steps

1. Spawn a rifle with a scope for better bug observation.
2. Spawn an iron helmet and a combat divingsuit (Pay attention to the spawning order, as it will affect the order in which items override the character's ObstructVisionAmount.)
3. Equip the iron helmet and then aim down sight to observe the field of view. Then, equip the combat diving suit, the field of view will expand.
