What happened?

1. Updated from Flame 1.18.0 to 1.21.0 (so issue was not present on 1.18.0)
2. During game session, flame randomly can remove my components (I have no clue why that happens on 1.21 and not on 1.18)

What do you expect?

I expect to know the reason why the component is removed. Both removeFromParent or onRemove are NOT called on removed components. So they just dissapear from World children set. Maybe Flame introduced some sort of garbage collector?

How can we reproduce this?

To be honest, I have no idea, maybe you can give me a clue why that can be happening.

What steps should take to fix this?

Make World's children set immutable and all add or remove operations can be logged if debug is true?

Do have an example of where the bug occurs?
