Steam Wcml Birmingham To Crewe (some) Route Tasks/areas Unavailable

I've recently started this route on PC and as I mostly like to do on a route I started the route task (collectibles) run.
One of those requires you to find little yellow robots (looks like a self-driving lawnmower) -sadly cannot remember the right terminology as the route tasks do not even appear on my profile in game-
Anyways, the one near Galton Bridge required me to God mode spawn a loco there but the one after that in Sandwell & Dudley remains locked behind an invisible barrier...

Hoping this will reach DTG somehow and hopefully somewhere in the future maybe a fix?

or be Neal8TV/TrainsimMania; they seemed to get it just fine
