Prefab reference lost and become fake null.

Some prefab references are lost, and shown as None. But if you reimport the prefab, they will be normal.

Then if you delete the Library directory of the project and reopen it, the prefab reference will be lost again.

Our jenkins can’t function normally because of this problem.

2.Import the ReferenceLosing.unitypackage in attachments,

3.Select Asset/Prefabs/test01, and we can see some elements in the dictionary and list is null.
