Why does this script only clone the model when I try it in Studio and not in game?

The script below should clone a model from serverstorage into workspace, this way I could reduce lag because unnecessary parts will be in serverstorage. It should clone it when I touch a certain part that is in workspace. (CanCollide = false) This works in Studio but when I try it in game nothing happens when I walk through the part.

Script:

x = 0
game.Workspace.TerrainButton1.Touched:connect(function(part) -- This clones the Terrain
	local parent = part.Parent
	if game.Players:GetPlayerFromCharacter(parent) then
		if x ~= 1 then
			local terrain1 = game.ServerStorage.Terrain1
			terrain1:clone().Parent = game.Workspace
			x = 1
		end
	end
end)


game.Workspace.HordeButton1.Touched:connect(function(part) -- This clones the Zombies
	local parent = part.Parent
	if game.Players:GetPlayerFromCharacter(parent) then
		if x ~= 2 then
			local horde1 = game.ServerStorage.Horde1
			horde1:clone().Parent = game.Workspace
			x = 2
		end
	end
end)


game.Workspace.RemoveButton1.Touched:connect(function(part) -- This deletes both the terrain and the zombies
	local parent = part.Parent
	if game.Players:GetPlayerFromCharacter(parent) then
		x = 2
		local horde1 = game.Workspace.Horde1
		local terrain1 = game.Workspace.Terrain1
		if horde1 ~=nil then
			horde1:destroy()
		end
		if terrain1 ~= nil then
			terrain1:destroy()
		end
	end
end)
