Scene changer CS file causes lighting errors when changing scenes

Hey guys! Sorry if the title is a bit hard to understand.
First, I want to say that by “lighting error” I don’t mean errors in the Unity Console. I mean the lighting looks terrible and is too dark.

I have a script named LevelChanger.cs that allows me to easily switch the scene when a certain GameObject has been touched (as in, the given GameObject is in the collision box). Here’s what the script looks like:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.SceneManagement;
using UnityEngine.UI;

public class LevelChanger : MonoBehaviour
{

    public string sceneToLoad;

    void OnTriggerEnter(Collider target)
    {
        Debug.Log("You have hit the scene changer! Totally not written by me!");

        if (target.tag == "Player")
        {
            SceneManager.LoadScene(sceneToLoad, LoadSceneMode.Single);
        }
    }
}

The scenes that are important are: Tutorial.unity and Lvl1.unity. Whenever I look at Lvl1.unity in the editor and in the editor playtest mode, it looks just fine. All the lighting is good and everything. But when I enter Tutorial.unity, touch the GameObject with the script above and go to Lvl1.unity via the game, all of the lighting is messed up. The front (maybe front, idk) sides of cubes are completely black whilst like 1 side of all of the cubes are green. It looks terrible but you can see what it looks like because I attached the screenshots to this post. Assuming you can see the name of these screenshots, BlimpsError1.PNG is what the scene looks like with correct directional light and BlimpsError2.PNG is what it looks like with the bugged directional lighting that LevelChanger.cs gives me. Any help would be appreciated!


Editor has a bug with lighting if you auto-bake.

You can verify that this is the case here by making a build to play outside of the Editor.

The current first scene will look correct, but when as you load or reload a scene, that subsequent scene will be darkish.

Turn off auto-bake and bake your lights if you wish to see correct lighting in the Unity Editor.
