For nodes with an FGameplayTag or FGameplayTagContainer pin, when changing the tag value (Pin->DefaultValue) and triggering Undo/Redo, the pin modification is not undone. Rather, it undoes the previous action. This is a regression: in UE 5.2.1 tag undo worked correctly.

Steps to Reproduce

In UE 5.3.2:

  • Open a blueprint graph
  • Create a node with a gameplay tag pin, for example Make Literal Gameplay Tag
  • Set the tag value to anything other than None
  • Press Ctrl + Z to undo
  • Observe: The action undoes the node creation, rather than the tag value modification
  • Expected: It should just undo the tag value modification


  • Add the Make Literal Gameplay Tag node
  • Do another action, like deleting a BeginPlay node
  • Change the gameplay tag value
  • Press Ctrl + Z
  • Observe: it undoes the BeginPlay node deletion
  • Expected: it should undo the tag value modification

The same repro steps apply for FGameplayTagContainer, for example Make Literal Gameplay Tag Container.
