Game crashes when adding sprite to a group

Game crashes with this error after adding a sprite to a group.

Uncaught Error: [object Object]addChildAt: The index 2 supplied is out of bounds 0
    at c.Group.d.DisplayObjectContainer.addChildAt (phaser.min.js:3)

I need to add a sprite to specific index of a group.

var entity = game.add.sprite(x, y, (teamId == 1 ? "a" : (teamId == 2 ? "b" : "c"))+"_"+skinId);
entity.scale.set(teamId==0?1:0.5);
entity.anchor.set(0.5, 0.5);

game.physics.box2d.enable(entity);
entity.body.angle = angle;
if (teamId != 0){
	entity.body.setCollisionCategory(teamId == 1 ? 2 : 3);
}

if (name){
	entity.nametag = game.add.text(entity.x, entity.y - 35, name, { font: "16px Ubuntu", fontWeight:'bold', fill: "#ffffff", stroke:'#000000', strokeThickness:2.5, wordWrapWidth: entity.width, align: "center"});
	entity.nametag.anchor.set(0.5);
}

entity.data.entityId = entityId;
entity.data.teamId = teamId;

if (entityId == user.entityId){
	game.camera.follow(entity);
	if (teamId == 2){
		entity.body.setCategoryContactCallback(2, game.state.getCurrentState().onPlayerHit);
	}
}

game_name.entities.add(entity, false, entityId);

I even tried using addAt, it doesn't work either.

 

Is this a bug?

You can't add outside of the last index. For an empty group, you can only add at the first index.

I've found another problem, sprite became invisible when you add it to a group.

Game.js (create):

game_name.entities = this.add.group();

Network.js is the same as the first post (except group.add, i only call it with sprite now.)

 

Edit: It's because group was created in another state, i've fixed it.
