When using an Editor Utility it appears that the user cannot write to the Undo Buffer.
Result: The actor will undo its position and rotation (skipping any of the changes that would have been written to the Undo buffer (Undo history could also be used to look for changes))
Expected: The Undo buffer would have been written to, leaving the cube to only undo its rotation (as this is all that was changed in the blueprint provided )
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-72322 in the post.
