The way I do it is I have identical hidden array variables within my GameHUD and within the SaveGameObject. When I begin the process of saving the first thing I do is check which save I am loaded in (save1,2,3,etc…) or if its a new game.
Then I use the clear array node on all the SaveGameObject arrays first before loading it up with the GameHUD array data. Both set of arrays within these Blueprints are named the same because its easier for me to grab and set them, when the only thing that changes is the target.
I also clear the GameHUD Arrays when loading the data in as well to make sure there isn’t anything there when I reload the data arrays from the SaveGameObject. Basically it’s the above process but in reverse and it looks about the same.
So maybe try clearing the arrays first before saving and loading and see if that helps. I can save multiple times on the same game slot with no issues even after changing my inventory items, so it can be done just don’t give up. If you still can’t get it I’ll post my screenshots for my saving BPs.
