This is my first post here so I don't know is this right - but all my trains were dissapeared !!! What can I need to do???
have you done a relogg? After a relogg you see your trains again.
And we know the problem. It is a graphical bug, only, so you get the income of your trains further.
Do you remember, how the trains disappeared in your case?
When you realised, that your trains disappeared. What was the last thing you did?
