Overwrite routing not works on production

Hi!
I have a plugin wich works pretty fine on local solution.
It overwrite route like:

 public int Priority
        {
            get
            {
                return 10;
            }
        }

        public void RegisterRoutes(RouteCollection routes)
        {
            routes.MapLocalizedRoute("Plugin.Shipment.ShipmentRestrictions.OpcSaveBilling",
                "checkout/OpcSaveBilling/",
                new { controller = "CheckoutShipmentRestrictions", action = "OpcSaveBilling" },
                new[] { "Nop.Plugin.Shipment.ShipmentRestrictions.Controllers" });
 
        }

But on production its not work. Could u please tell me how can i retrieve full list of route on productions?
How can i debug this problem?

You have to ensure that your plugin route added in the route collection ==> you can upload Nop.Core.dll and Nop.Web.dll with this plugin dll it will force restart or edit a bit(i.e press space) Global.asax ..that will restart app.

And also could ensure is there no other plugin that overrides same route?
