Squash the Creeps 3D Score Bug

[J-John1]

Your Godot version:
4.0.2.stable

Issue description:
While making the "Squash The Creeps 3D" tutorial, I had an issue with the following piece of code, when trying to use it in the ScoreLabel to update the current score:

for index in range(get_slide_collision_count()):
	# We get one of the collisions with the player
	var collision = get_slide_collision(index)
	
	# If the collision is with ground
	if (collision.get_collider() == null):
		continue
	
	# If the collider is with a mob
	if collision.get_collider().is_in_group("mob"):
		var mob = collision.get_collider()
		# we check that we are hitting it from above.
		if Vector3.UP.dot(collision.get_normal()) > 0.1:
			# If so, we squash it and bounce.
			mob.squash()
			target_velocity.y = bounce_impulse

When playing the game, each squashed creep increases the score by a random integer between 1-3 points each time. I believe this happens because the squashed signal is being emitted for each collision count. I tried putting "return" at the end of the "if collision.get_collider().is_in_group("mob"):" statement and this seemed to fix the problem. Due to the limitation of my programming experience, I believe it would be for the better if someone more knowledgeable could check the cause for this problem.
