Coroutine wrong Behavior when scene is loaded

Question

Ok so I have this coroutine :

 IEnumerator ShowCharTraits()
    {

        while(!hasPlayerChosen)
        {
            yield return null;
            trait         


        

Answer 1

Ok how do I explain this. I have a singleton that acts as a data holder. While developing the scene with the game manager I had attached the singleton to the gamemanger object that hold a bunch of scripts. Now when I made the main menu I ofc added my singleton to it so I can carry info to the game scene and because of this my whole game manger object was being deleted. This is the culprit from the DataHolder :

 void Awake()
    {
        if (instance == null)
            instance = this;
        else if (instance != this)
            Destroy(gameObject);//This right here.

        DontDestroyOnLoad(gameObject);
    }

So I changed that line to Destroy(gameObject.GetComponent(instance.GetType()));
