Godot 4 Multiplayer: Spawned objects are different on Client vs Host (RNG Desync?)

Help

Hi everyone, I’m working on a server-authoritative weapon spawner in Godot 4.5. My goal is simple:

Host waits 5 seconds * Host rolls a dice (60% chance M4A1, 40% Pistol). * Host instantiates the weapon and adds it as a child. * MultiplayerSpawner should replicate this exact weapon to all clients.

The Problem: The clients are sometimes spawning a different weapon than the host (e.g., Host sees M4A1, Client sees Pistol). It seems like the clients might be running their own RNG logic or the MultiplayerSpawner is not syncing the specific scene choice correctly.

*

I couldn’t solve the problem. I consulted ai but it didn’t help. I would be very happy if you could help me.

*

code:

#------------------------------------------------------#

extends Node3D

@export var m4a1_scene: PackedScene
@export var pistol_scene: PackedScene

func _ready():
	if multiplayer.is_server():
		await get_tree().create_timer(5.0).timeout
		spawn_silah()

func spawn_silah():

	if not multiplayer.is_server():
		return

	var sans = randf()
	var secilen_silah = null
	
	if sans <= 0.60:
		secilen_silah = m4a1_scene.instantiate()
		print("Sunucu M4A1 seçti.")
	else:
		secilen_silah = pistol_scene.instantiate()
		print("Sunucu Pistol seçti.")
	
	if secilen_silah:
	
		secilen_silah.global_position = $MeshInstance3D.global_position
		add_child(secilen_silah, true)		
		rpc("mesh_gizle")

@rpc("call_local", "reliable")
func mesh_gizle():
	$MeshInstance3D.visible = false

but how would the client run their own RNG logic if it is all done on the server? Is the multiplayer server being called by every single client individually (this might be the problem) or is it just running once on the main scene then another script hands them out to clients?
