[Scripting Question] New Status Effect : Disease

[Jenkkrystal]

Hi, I am trying to implement Disease as a new Status Effect. Mainly, I have achieved almost everything.

A Pokemon suffering from Disease will take damage each time it uses a move of a type different than either of its two types. But the movement in question will still take place.

The point is I have successfully implemented the new status effect, but I have not managed to create a movement capable of causing it.
I can't find the cause of the problem.
If I manually set the Disease status with the Debug menu, so I can check it, once in the battle, and it's working just as I want.

This is for v. 17.2
Here is the most important code parts, I mostly used a variation of the Freeze code:

PBStatuses

  module PBStatuses
    SLEEP     = 1
    POISON    = 2
    BURN      = 3
    PARALYSIS = 4
    FROZEN    = 5
    BLEED     = 6
    ENFERMO   = 7

    def PBStatuses.getName(id)
      names = [
         _INTL("saludable"),
         _INTL("dormido"),
         _INTL("envenenado"),
         _INTL("quemado"),
         _INTL("paralizado"),
         _INTL("congelado"),
         _INTL("sangrando"),
         _INTL("enfermo")
      ]
      return names[id]
    end
  end

PokeBattle_Battler
Below the code of Freeze

if self.status==PBStatuses::ENFERMO
      if thismove.canCurEnfUser?
        PBDebug.log("[Move effect triggered] #{pbThis} se recuperó usando #{thismove.name}")
        self.pbCureStatus(false)
        @battle.pbDisplay(_INTL("¡{1} curó la enfermedad!",pbThis))
        pbCheckForm
      elsif @battle.pbRandom(10)<1 && !turneffects[PBEffects::SkipAccuracyCheck]
        self.pbCureStatus
        pbCheckForm
      elsif !thismove.canCurEnfUser?
        self.pbContinueStatus
        PBDebug.log("[Status] #{pbThis} permanece enfermo")
        if ((thismove.type)!=(self.type1) && (thismove.type)!=(self.type2))
        pbEnfermoDamage
        @battle.pbDisplay(_INTL("¡#{pbThis} recibió daño de la enfermedad!")) 
        PBDebug.log("[Status] La enfermedad causó daño a #{pbThis}")
        return true if !self.isFainted?
        return false if self.isFainted?
        end
        #return false
      end
    end

There are other minor additions to the code, but I think these are the most important.
I need help to get a move causing the Disease (Enfermo) status successfully.
