Remote event works on one game, but not the other

EDIT: WAIT WAIT WAIT I FIGURED IT OUT KINDA
okay so disabling streaming enabled(?) fixed it??? why? what does streaming enabled even do? break scripts? whats the point of it? to be a pita? why does it exist? to make peoples lives harder??

I am making a very clunky and unorganized bullet script, and IT WORKS PERFECTLY FINE ON ONE GAME, but if I copy EVERYTHING, all of the scripts, not just the code, literally the INSTANCES themselves and paste it into a new template, it just doesn’t work.

Client error, bullet is for SOME reason NIL

game.ReplicatedStorage.TracerEvent.OnClientEvent:Connect(function(bullet,color)
	print(bullet,color)
	Tracer(bullet,color)
end)

Server:

	local c = script.Bullet:Clone()
	c.CFrame = cf
	c.PointLight.Color = player:GetAttribute("Color")
	c.Parent = workspace.Terrain
	
	game.ReplicatedStorage.TracerEvent:FireAllClients(c,player:GetAttribute("Color"))

Again, this code works, ON THE OTHER GAME WHYYYYY.
This LITERALLY is the EXXXXACT SAME setup SO WHY DOESN’T IT WORK

Like is there some setting I need to check??? Whyy bruh???
