    Resolution Note (fix version 2019.3):

    The use of DestroyImmediate(object) within Undo groups is undefined behaviour as it will permanently destroy the asset.
    It is recommended to always use Undo.DestroyObjectImmediate(object) to ensure that the destroyed object is stored on the undo buffer and can be fully restored.
    Fatal error message added.
