There is an Editor Subsystem defined by Blueprint Attributes plugin whose role is to take care of Attribute properties renames in Blueprints. This system is called internally "Referencer Handlers".

• Detects Attribute renaming in the Blueprint Editor.
• Replace previous references to the renamed Attribute in Gameplay Effects.
• Displays a list of modified properties and Blueprint nodes (K2Nodes) in the message log with clickable links for easy navigation to the referencers.
