I hate that, and its why I play with the no connection mod enabled. Lol
I only use it to make sure I can delete a nuisance road should I need to.
Although I have been known to delete a road to stop goods walking to cities instead of taking my train…. Still don’t know why it does that. Lol (train travels at 100kph, walking 5kph…Hmmmmm, the train depot is even unloads in the middle of blue zones, but cargo will still try and walk it. Lol)
If you’re not fussed about achievements, then I suggest enabling the mod. If you’re trying to unlock the 1900 and 1950 start, then you just need to persist. Lol
