FixPrefab is an easy to use tool for fixing broken prefab links. Prefab links from scene view and assets containing the prefabs sometimes get broken from usual activities.
This script will let you select the broken prefab from your scene view, then a prefab you want to replace it with(it can by a different prefab if you choose) then its fixed! You also have the option to keep the original transform or have it deleted.
