PrefabInstanceUpdated.prefabInstanceUpdated doesn't work well in 2018.3

Hi,

I found the something about

PrefabInstanceUpdated.prefabInstanceUpdated

:

1. If I open a prefab by double click or click `Open Prafab` in the prefab's inspector it will bring me to a new prefab mode edit scene. In this scene view there is a `Save` button on the top. When I finish editing the prefab and click the `Save` button the prefab will be saved but the prefabInstanceUpdated event won't fire.
2. If I open a new scene and then drag the prefab into the scene to create an instance. After doing some modification to the instance and click `overrides/apply` in the inspector the prefab will be saved as well and the prefabInstanceUpdated event fires.

I want to do some post process to the prefabs after it saved/applied but there seems to be no event to tell that in the new prefab edit mode. Any advises?

 

I just want to do some automatically stuffs, such as check the compnents' properties, after prefab updated or saved.
