[MaxSmiley]

Hello! I have a problem with my game.
When the player start a double fight with a trainer, the battle begin and the trainer sends his Pokémon but this error appears:

Exception: RuntimeError

The explanation is simple: you forgot to declare the constant called "FOEBASED1_Y" in "PokeBattle_SceneConstants" script section.
