I've got a state machine set up that I'm having an issue with. I have a Start scene, a Level_01 Scene, and a GameOver Scene. Each scene has a corresponding state. When the game starts, it sets the game to the Start scene. When I click the start button, it loads the Gameplay state. The game plays fine, but when you lose, the GameOver state does not load, the game continues to run, and I get one error that says the Game Manager has been destroyed and I am still trying to reference it. I have my managers set up on a Singleton pattern and I'm not sure how it's getting destroyed. This is my first time using both the state machine and the singleton, and I also have very little experience switching between scenes so I may be doing something simple wrong. The main thing I can tell you is that the currentState variable is coming back as null when I go to hit the GameOver state, and that the code is not even getting far enough to hit the OnDeactivate for the GamePlay state (probably because currentState is null). I'm really out of ideas on this one and haven't been able to find anything useful online. Hopefully someone can show me what I'm doing wrong. Thanks!
