[Error] Ally Switch Causing Error

[silverlime]

For some reason, when Ally Switch is used, an error message pops up and the user does not switch places with its partner (its sprite disappears but this may be part of the animation used and not the error). I have not edited the MoveEffects code for Ally Switch, but I must have changed something else that is causing it not to work. Here is the error message:

[Pokémon Essentials version 17.2]
Exception: NoMethodError
Message: undefined method `pbUpdate' for nil:NilClass
PokeBattle_MoveEffects:1807:in `pbEffect'
PokeBattle_Battler:5002:in `pbUseMove'
PokeBattle_Battler:5001:in `logonerr'
PokeBattle_Battler:5001:in `pbUseMove'

PokeBattle_Battle:4225:in `pbAttackPhase'
PokeBattle_Battle:4222:in `each'
PokeBattle_Battle:4222:in `pbAttackPhase'

This is the code for Ally Switch as present in PokeBattle_MoveEffects:

class PokeBattle_Move_120 < PokeBattle_Move
  def pbEffect(attacker,opponent,hitnum=0,alltargets=nil,showanimation=true)
    if [email protected] ||
       !attacker.pbPartner || attacker.pbPartner.fainted?
      @battle.pbDisplay(_INTL("But it failed!"))
      return -1
    end
    pbShowAnimation(@id,attacker,nil,hitnum,alltargets,showanimation)
    [email protected][attacker.index]
    [email protected][attacker.pbPartner.index]
    temp=a; a=b; b=temp
    # Swap effects that point at the position rather than the Pokémon
    # NOT PerishSongUser (no need to swap), Attract, MultiTurnUser
    effectstoswap=[PBEffects::BideTarget,
                   PBEffects::CounterTarget,
                   PBEffects::LeechSeed,
                   PBEffects::LockOnPos,
                   PBEffects::MeanLook,
                   PBEffects::MirrorCoatTarget]
    for i in effectstoswap
      a.effects[i],b.effects[i]=b.effects[i],a.effects[i]
    end
    attacker.pbUpdate(true)
    opponent.pbUpdate(true)
    @battle.pbDisplay(_INTL("{1} and {2} switched places!",opponent.pbThis,attacker.pbThis(true)))
  end
end

Change attacker and opponent to "a" and "b":

a.pbUpdate(true)
b.pbUpdate(true)

Also, Ally Switch will be improved in v18, it still has some bug on its script.

Ok so I changed this and it got rid of the error message (I also had to change attacker.pbThis & opponent.pbThis to a & b as well for the battle display text). However, they aren't switching places.

Also I thought Pokemon Essentials was discontinued and didn't know they were making a v18. I guess they worked out copyright issues now.
