Repro steps:
- Create a Blueprint Structure in the content browser with a few example variables
- Create a Datatable from that struct and add a few rows
- Return to your struct and delete a variable
- Check the Datatable - the column should have been removed correctly
- Press Ctrl-Z to undo the variable deletion (it reappears in the Struct)
- Note that all rows in the Datatable are removed
Expected: Performing an undo should restore the variable and not clear the Datatable.
Note: It’s sometimes possible if pressing Undo again to retrieve the Datatable contents if you were performing other struct/datatable actions previously.
