Hey @VintageSCollecto!
I think there’s a confusion somewhere. I didn’t mention it for the first time here:
But now I think it’s time to clear things up.
Take a look at this explanation again:
The snippets I provide are to be integrated with your existing project. You obviously don’t use debug keys for your mechanics, the one I used was just to indicate the start of the execution chain. You can use the function it triggers however you like.
Let’s do this then, since your next goals will also use our existing functions, I’ll explain what you need to do and you try to implement it okay? I think that’d be better for you as you’d be actively learning 
Just trigger the save function again before the Quit Game node then. And we already save the player start location upon opening levels so that second thing won’t be a problem.
Simply place a delay before our logic inside the level blueprints. However you’d also need to open the last level along with setting the actor’s transform that way, otherwise the player character will be teleported to a meaningless location in the new map.
Now about your questions & issues:
Yep!
Sounds like you’re not saving then. Make sure to tick the Looping checkbox inside our Set Timer by Event node, and set the Auto Save Interval variable’s default value.
If you keep encountering issues, share your setup for us to take a look
