Hi gax and Neldot,
Thank you for your input on my problem. 😀
I have tried everything to get around this, and I agree with Neldot that this seems like a bug in the game.
It have happen a few time for me now on any size of map.
I’m happy for you gax that you do not have this problem, and I hope you do not get the problem as it is quite annoying. 😉
Nevertheless, it really do not help me that you do not get it. 😉 In addition, of course I have tried all possible solutions I could think of. As you see in my second post, I even added new track, a new tunnel (very expensive) to get two track and then tried, still the same thing. :-p
