Where is this route come from? If from T:ANE, all you have to do is open it there, and see if there are any red boxes If not, look at the place where the yellow box is in 19 and extrapolate what is in T:ANE There is a possibility that assets working in T:ANE are faulty in 19, but I doubt it, most likely is that some dependencies were not imported and the program shows the fault. Use your logic.
