Brilliant, thank you
There is no need for a pre-load on this as there isn´t too much stock or much going on. I assume that you have all requirements? Try loading up the route in the Motherwell area as a free roam scenario, having a fly about, exiting out the free roam then loading up my scenario to see if that works.
Good luck,
Simon
