Hey everyone! I see this post is old as hell xD but for everyone who has this issue:
If you pause your game with the Set Game Paused Node, it can’t complete codes like spawn points, clearing widgets, etc.
If you have a ‘Back to Main Menu’ Button, make sure the first thing you do is to unpause the game (Set Game Paused to False)!!!
Then it should work perfectly fine!
Cheers yall and happy coding!
