Seems like I can’t upload any videos so I’ll just redirect you to Reddit where I first uploaded this question:
Reddit Post with the bug and code

Player attract enemy code:

func attract_to_player(delta):
    # Accelerate towards player
    curEatSpeed = lerp(curEatSpeed, eatSpeed, eatAccel * delta)

    # Calculate direction towards player
    var direction = (player.position - position).normalized()

    # Smooth movement out
    var curveDir = direction.lerp((player.position - position).normalized(), eatCurve)
    position += curveDir * curEatSpeed * delta

    # Make enemy smaller over time
    var distPlayer = position.distance_to(player.position)
    var scaleFactor = clamp(distPlayer / 200.0, 0.5, 1.0)
    scale = scale.lerp(Vector2(scaleFactor, scaleFactor), 0.1)

Enemy instantiate code:

func other_function(): # Not the real function, just a slice of it
    var enemyInstance = get_enemy(enemyType)

    # Spawn
    enemyInstance.position = get_lane(lane)
    enemyInstance.handedness = handedness
    add_child(enemyInstance)

func get_enemy(enemyType):
    var enemy
    match enemyType:
    "BaseEnemy": enemy = BaseEnemy.instantiate()

    return enemy

What do you mean by “wont work” and the reddit-post is deleted
