Components under a "Publisher" will not get a published value

[HugoVG]

let's say we this stack of components it should notify CharacterAnimatorComponent and SpeakingColorChangerComponent but currently it will not notify SpeakingColorChangerComponent Why does it do that? most components will Start once, and that's when they are made

public override void Start()
{
    _components = GetComponents<ISpeakingAwareComponent>(); //<--- 
    //...
}

after that they will never update.

Solution

On new Component Update all previous components.

Potentential issues

A component might do a "Should only happen once" event twice
