I open up MWG in surveyor and the map loads quite slow and has lag. I'm not sure if it has to do with these errors or not but maybe the pictures will help address the problem.
So I double checked everything and I have no faulty industries or products and the route still has errors upon loading. The route is error free and no missing dependencies are showing, but I keep getting those errors
If that's the case, you have a defective product. Do a CMP search for the products you have added most recent, and start removing them. Check if you have the product "rebar," if so delete it and check your routes.
