[Scripting Question] Multiple forms and movesets

[HarmonyConcept]

I am trying to define several movesets for species based on a criteria of differentiation (for example, between a shiny and a non-shiny).
Is there a way to make something like this work:

MultipleForms.register(:SANDSHREW,{"getMoveList"=>proc{|pokemon|
  movelist=[[1,:DRAGONHAMMER],[1,:SEEDBOMB],[1,:BARRAGE],[1,:HYPNOSIS],
            [1,:CONFUSION],[17,:PSYSHOCK],[27,:EGGBOMB],[37,:WOODHAMMER],
            [47,:LEAFSTORM]]
  for i in movelist
    i[1]=getConst(PBMoves,i[1])
  end
  next movelist [COLOR="Red"]if pokemon.isShiny?[/COLOR]
}

When I give the player 2 Sandshrews, one of them being shiny and not the other:

$Trainer.party=[]
pkmn=PokeBattle_Pokemon.new(:SANDSHREW,46)
pkmn.makeShiny
$Trainer.party.push(pkmn)
pkmn2=PokeBattle_Pokemon.new(:SANDSHREW,46)
$Trainer.party.push(pkmn2)

... BOTH Sandshrews always acquire the same moveset!

I've tried small variations such as this one:

"getMoveList"=>proc{|pokemon|
  [COLOR="Red"]next if !pokemon.isShiny?[/COLOR]
  movelist=[[1,:DRAGONHAMMER],[1,:SEEDBOMB],[1,:BARRAGE],[1,:HYPNOSIS],
            [1,:CONFUSION],[17,:PSYSHOCK],[27,:EGGBOMB],[37,:WOODHAMMER],
            [47,:LEAFSTORM]]
  for i in movelist
    i[1]=getConst(PBMoves,i[1])
  end
  next movelist
  movelist=[]
},

I always got the same results. Either the 2 Sandshrews, the shiny and the non-shiny one, learn this moveset, or they don't.

This part of code is used in various Delta/Alolan custom scripts and seem to never work properly.

Does someone know a way to make this work (other than updating to v17?)

The Pok?mon are given their moves when they're created, which happens before you can make one of them shiny.

After making your first Pok?mon shiny, write pkmn.resetMoves.
