Question
` I am attempting to pass the host to another client when the host leaves the lobby. Currently when the host leaves the scene is “closed” and a grey screen appears. I create the lobby and handle joining through my main.gd:
extends Node2D

I believe the issue may lie in main.gd _on_host_pressed(). I’m spawning the level only by the host. - ms.spawn(“res://scene/level.tscn”)
I think the issue is when the host leaves, other players no longer have access to the level. I there a way to pass the current state of the level to the new host assigned by the Steam lobby?
Sorry for my incompetence’s, first time trying this and am having trouble finding resources surrounding this.
