Incidentally and odd enough, I’ve had no problems so far with Train Fever, but I’ve got some with Cities:Skylines. One is what also happened with CiM2: if two ships go near each other they get interlocked when they arrive to a harbour. The solution of the game is to vanish the first one when some time passes!
The second is worse and has started to happen with the last patch: 1.0.7a. Whenever I load a game, after a few seconds, the game crashes. That patch was retired by the developers and reintroduced as 1.07c with all the problems solved… To no avail… It still crashes to desktop. Since I can’t go back to the game unpatched, I can’t play the game any longer, which is frustrating…
In conclusion and in my personal experience, this topic is unfair. But I guess that experiences may vary…
