Unknown as to what's causing this crash, but it's crashing the server I'm in, in multiplayer. This crash also crashed all connected clients.

I got a similar crash in 0.17.4 version. Game shuts down when train reaches the station. Tried it more than once.
Attached a savefile, just place some coal into train (there is a warning that the train is out of fuel)

I think I got the same type of crash on 0.17.4. Server and all clients (both linux and windows) crashed at the same time. Unfortunately on linux machines no crash file was generated and I have no access to windows logs. I also attach the last part stdout/err of the linux headless server. All files end abruptly, so they are probably useless.

It was multiplayer game so two things occurred during the crash:
* I connected water pipe to the heat exchanger (no complicated steam/water/other stuff nearby that could confuse the algorithm) <- irrelevant
* My friend (kazik) was in a train and was travelling with shift-click to the station. Crash occurred at the moment of arrival. <- probable cause
