UnityEvent 未在检查器中显示动态方法调用（其他 Unity 事件也部分损坏）

我有这个团结活动

[Serializable]
public class UnityEventString : UnityEvent<string>
{
}

在此使用哪个MonoBehaviour

public class EventListenerString : MonoBehaviour, IEventListener<string>
{
    //some more code
    public EventString Event;
    public UnityEventString Response;
    //Some more code
}

问题是，它没有在检查器中将此方法显示为动态。

    public void Show(string key)
    {
        _Show(Animator.StringToHash(key));
    }

    public void Hide(string key)
    {
        _Hide(Animator.StringToHash(key));
    }

I used to use this pattern for my other events too, and they worked fine until today. Currently, there are the right methods in the inspector, from earlier this week when i programmed. But today everything stopped working for that.

它还停止了对带有测试的普通测试对象的工作MonoBehaviour仅用一种方法。

But it still works with that one here

这里发生了什么？

我认为 Unity 2019.2.5 有问题，到 2019.2.4 为我解决了这个问题，所有动态事件都回来了。
