I was setting double stations, and disabling the back Fuel station via signal.
Copy/Paste to the next one in the line caused a crash.
9150.336 Error MainLoop.cpp:1142: Exception at tick 443262: The mod Automatic Train Fuel Stop caused a non-recoverable error.
Please report this error to the mod author.
