Doesn't always do it, maybe a race condition of removing the station before it processes the train is gone?

Exception at tick 25161: The mod SSPP Logistics Train Mod (0.3.19) caused a non-recoverable error.
Please report this error to the mod author.

Just published a new release that should fix this issue. It wasn't actually anything to do with destroying a train, rather destroying a station just wasn't properly disabling its items for further processing until stations get re-polled. Let me know if you still have any issues :)
