Disclaimers

• I have searched the issue tracker to check if the issue has already been reported.
• My issue happened while using mods.

What happened?

Cyborgworm, Fractalguardian_emp, Guardianrepairbot and Portalguardian do not have empvulnerability (affected by Affliction emp)
Although Fractalguardian_emp can cause emp but it does not cause emp affliction
not sure if it is intended. they also don't have IsMachine="True" which means they can have afflictions like organdamage and psychosis

Reproduction steps

1. disableenemyai
2. spawn Portalguardian cursor
3. giveaffliction opiateoverdose 2000 Portalguardian
4. control Portalguardian

One reason for this seems to be that Fractalguardian_emp uses EMP (risk of self-EMP or friendly fire EMP) so it may need some additional (code) work to avoid Fractalguardian_emp, Guardianrepairbot and Portalguardian getting EMPed by Fractalguardian_emp

Cyborgworm is debatable whether or not EMP should affect it, since it's not fully a machine, it's more creature than machine.

Anyways, we will take this forward in the future after some discussion on what work it actually requires.

EMP used by Fractalguardian_emp won't cause EMP affliction so it shouldn't affect themselves
but emp affliction maybe too good to deal these creatures
It causes internal damage multiplyafflictionsbymaxvitality and constant stun

EMP used by Fractalguardian_emp won't cause EMP affliction so it shouldn't affect themselves

The alienturretammoemp ammunition used by guardianempcannon and the TurretBarrel limb in Fractalguardian_empDefaultRagdoll.xml does cause an EMP of empstrength="0.5" in the explosion effect:

      <StatusEffect type="OnBroken" target="This">
        <ParticleEmitter particle="faradayfx" anglemax="360" distancemax="300" scalemultiplier="5,5" particleamount="40" />
        <sound file="Content/Items/Weapons/ExplosionMedium3.ogg" range="10000" dontmuffle="true" />
        <Explosion range="500.0" structuredamage="0" force="20.0" empstrength="0.5" applyFireEffects="false" underwaterbubble="false" shockwave="true" flames="false">
          <Affliction identifier="stun" strength="1" />
        </Explosion>
        <Remove />
      </StatusEffect>

but it does not cause emp affliction
empstrength won't affect creatures
emp grenade has both

<Explosion range="500" force="5" empstrength="10" applyfireeffects="false" flames="false">
  <Affliction identifier="explosiondamage" strength="10" />
  <Affliction identifier="stun" strength="5" />
  <Affliction identifier="emp" strength="100" multiplybymaxvitality="true" />
</Explosion>

Hmm alright, in that case you might be right, I'll need to check with the person that actually implemented the fractalguardians in that case.
