Strange problem with LocalStorage?

Hey, I'm almost done with a big game and I've encountered a strange problem. I can't figure out how to fix it without major changes to the structure. Any ideas?

I've attached a screenshot of the events and the problem. If the "Close Browser" option works in one line, but not in another, that means the events aren't working at a certain point, and those events involve loading a save file for the entire game.

Another strange thing is that I have a button to reset all my game progress, and if I press it, the game works fine and my scheduled tutorial starts, but if I exit the game and re-enter it, the screen is black again and the code doesn't work in the place shown in the picture above.

That would seem to indicate the specified key does not exist.

You can check that by seeing if "On item missing" triggers instead.

To avoid abuse, some browser features only work in a user input trigger, like a click or a touch - or within a certain time limit after the user input. Closing the browser window may be one of them.
