Question

I have an autoload like this:

extends Node

var world_scene: PackedScene = load("res://scenes/world.tscn")

var levels
var main: Main

Here is my main.gd

extends Node3D
class_name Main

var main_menu: PackedScene = load("res://scenes/ui/main_menu.tscn")
var world: World
	
func _ready() -> void:
	Game.main = self

And finally world.gd (part):

func _ready() -> void:
	Game.main.world = self

I have a menu with “reset” button like this:

func _on_button_pressed() -> void:
	Game.main.world.reset_level()

While it is working fine inside Godot editor, when I export it to the exe, nothing happens on click. And there is many more errors relating to accessing variables via Game.main.world. Any ideas what is going on? Why it works in Godot but not in exe?
