Ah, yep. I was loading and saving directly to the `Example_Projects` folder as a test, and it was silently failing. I just tried saving in a totally different folder and worked fine. So I'm guessing you can't save in the app's location or any of its subdirectories.

I think it would be nice to pop up a warning message if the user tries to save here, as I had no idea what was going wrong. It might have been a known issue for you, but it wasn't known for me, haha. And yeah, getting no error message in response just leaves me scratching my head trying to figure out what went wrong.

Anyway, thanks for the help. Saving outside the app folder did the trick.
