[Error] Now even the default unchanged scripts have crash-causing errors?!

[SuperSpyroDragon64]

I download Pokemon Essentials, start a battle, and... I get this error message the second I try fighting the version of Brock that came with the engine version by default. Or any other trainer. Ever.

[Pokémon Essentials version 20.1]

Script error in event 5 (coords 27,4), map 3 (Aaa's house)
Exception: NameError
Message: wrong constant name Battle::Move::

***Full script:
TrainerBattle.start(:LEADER_Brock, "Brock")
Backtrace:

Here's the code it points to and everything is unchanged from the default.

  # This is the code actually used to generate a Battle::Move object. The
  # object generated is a subclass of this one which depends on the move's
  # function code.
  def self.from_pokemon_move(battle, move)
    validate move => Pokemon::Move
    code = move.function_code || "None"
    if code[/^\d/]   # Begins with a digit
      class_name = sprintf("Battle::Move::Effect%s", code)
    else
      class_name = sprintf("Battle::Move::%s", code)
    end
    if Object.const_defined?(class_name)
      return Object.const_get(class_name).new(battle, move)
    end
    return Battle::Move::Unimplemented.new(battle, move)
  end

[Pokémon Essentials version 20.1]

Let me know when somebody figures out how to make the engine work.

I am stuck in 2020, I still use v18 lol, but when I read the error message, it looks like there's a move that doesn't have an associated class with it. Do you know what move causes this?
In the PBS file for moves (probably still called moves.txt but I don't know) there is probably a move that misses a line in its definition. I see in the docs that it should have a "FunctionCode = Something" line, I assume that either this line is missing, or is left empty in one of the moves.

They changed the pbs for moves quite a bit in v20, but it functions the same.

That middle script says "Battle::Move::". Isn't that code from an older version? Shouldn't it be "Battle_Move" like in the bottom code? Did you update your scripts to v20? Or download an old plugin?

Unfortunately I'll be away from my computer for a week, so I can't check my v20 scripts to confirm thats the problem, but its a start.

Turns out this error was because I'd coded some Pokemon moves wrong. If they were on my party's Pokemon, the crash happened. I've fixed the two moves that were causing the errors.
