Bullet in editor does not behave the same in build.

Hello! This is going to be my first question so leave responses telling me how I can improve it.

I am trying to make a clone of the game RotMG (Realm of the Mad God) and I am starting to work on multiplayer. However, I encountered a weird bug that I came here to solve. I have implemented shooting and equipment, however, there seems to be a problem with either unity or my code. I have a basic projectile class:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Projectile : MonoBehaviour
{
    public bool ShotByPlayer;
    public int Damage;
    public float LifeSpan;
    public bool IsBase;
    public bool KilledItself = false;

    public int ShooterID;
    
    // Start is called before the first frame update
    void Start()
    {
        
    }

    // Update is called once per frame
    void FixedUpdate()
    {

    }

    public void SetSprite(Sprite newSprite) {
        gameObject.GetComponent<SpriteRenderer>().sprite = newSprite;
    }

    void OnTriggerEnter2D(Collider2D OtherCollider) {
        if(OtherCollider.gameObject.GetInstanceID() == ShooterID) {
            return;
        }
        GameObject EventManagerHost = GameObject.FindGameObjectsWithTag("EventManagerHost")[0];
        EventManagerHost.GetComponent<EventManager>().ProjectileHit(gameObject, OtherCollider.gameObject);
        if(IsBase == false)
            Destroy(gameObject);
    }
}

And it seems to work. Everytime a player clicks the following method is called

public void CreateBullet(Vector2 Position, Vector2 Velocity, int Damage, Sprite sprite, bool ShotByPlayer, Vector2 Size, float Range, int Id, Quaternion Rotation) {
        GameObject Bullet = Instantiate(GameObject.FindGameObjectsWithTag("BaseProjectile")[0]);
        Bullet.tag = "Projectile";
        Bullet.transform.position = Position;
        Bullet.GetComponent<Rigidbody2D>().velocity = Velocity;
        Bullet.GetComponent<Projectile>().ShotByPlayer = ShotByPlayer;
        Bullet.GetComponent<Projectile>().SetSprite(sprite);
        Bullet.GetComponent<SpriteRenderer>().size = Size;
        Bullet.GetComponent<Projectile>().Damage = Damage;
        Bullet.GetComponent<Projectile>().ShooterID = Id;
        Bullet.GetComponent<Projectile>().IsBase = false;
        Bullet.transform.rotation = Rotation;
        Bullet.transform.SetParent(GameObject.FindGameObjectsWithTag("ProjectileContainer")[0].transform); 

        Destroy(Bullet, Range / 23);
    }

So it sets the basic characteristics of a bullet: position, velocity, rotation, damage, sprite, size, and lifetime (Range)

And it seems to work fine in my editor, when I shoot it works fine and destroys itself after its lifetime is over. However, when I go to build my game and run it, it stops working (Kind of).

it still shoots and a bullet is created that looks fine and SOMETIMES destroys itself on time, however, oddly enough, only when I shoot forward, the bullet prematurely destroys itself and only when I shoot forward.

Can someone please explain why this is and how I can fix it?

So after A LOT of work, I managed to make a solution.
To all of the game objects that I want bullets to interact with I added a BLANK script to it called “CanBeHit” with no code.
Then, to my OnTriggerEnter2D method, I added this line of code.

if(Mathf.Round(transform.rotation[3] * 10) / 10 == 0.7 && 
    Mathf.Round(transform.rotation[2] * 10) / 10 == 0.7 && 
    OtherCollider.gameObject.GetComponent<CanBeHit>() == null) {
            return;
}

This basically checks if I am shooting up and if I am, and the object that we collided with cannot be hit, then just return, and keep ongoing.
Apparently, the issue is that whenever I shot upwards, there was some rogue collider in its way that caused it to prematurely get destroyed.

So I checked if the object that we hit and if it was a rogue collider and we are aiming upwards, flat out ignore it.

Still not sure why the rogue collider only affects bullet in build and not in editor though.
