I am changing scenes when the player loses to go to the game over screen then back to the into screen. However, I’ve noticed that going from an Singleton/Autoload has no issues but going from a regular scene will sometimes give me the error in the screenshot attached… This error will never occur on the FIRST time we go to the game over screen but it can occur anytime after that. I’ve asked a few people and it seems like the game is trying to do something while the scene is not in the current tree. Is there a way of finding out what node is being called or what function/logic is still being worked on while the scene is NOT in the tree? I’m seriously at a loss as to how to fix this bug. The game itself doesn’t crash but if you play again, it will crash at some point due to the amount of error messages or whatever is it trying to do.

Scene Transition

github.com

ja-brouil/TBS_GoDot/blob/master/Scenes/Transition/Scene Transition.gd

extends CanvasLayer

signal scene_changed
signal scene_loaded

onready var black_transition = $"Scene Changer/Black"
onready var animation_player = $"Scene Changer/Animation"

var current_scene

# Call when you want to change the level
# Path = file location for the next scene
# Delay = time between each scene
func change_scene(path, delay = 0.1):
	# Create the delay for timeout
	yield(get_tree().create_timer(delay), "timeout")
	
	# Play fade animation
	animation_player.play("fade")

Turn Manager where the game over is called

Rest of the code if required

I will be eternal grateful if someone can help me out

Use remove_child to hide the node instead of free.

current_node.free() #this looses current_node's reference
current_node = loader.instance() #current_node doesn't exist

Edit: Completely read that wrong, there’s no issue here. It might be because you used free instead of queue_free but I can’t see any reference to current_node whilst it’s freed.

I feel like a node is trying to process something when it’s time for the scene to change but I can’t seem to find what is trying to process.
