0.14.9 Trains lose schedule when no path found.

[Sabbie]

We're running a server with a pretty big factory ( [EU] /r/factorio MMO ) and when I logged in today all trains had lost their schedule.

At first we thought it was somebody trolling, but when it happened again I looked into it.

It seems that once a train get into a state where it cannot find a path, it will delete it's schedule. Once one train does that, it will very quickly deadlock the factory and destroy every train schedule there is.

I can not reproduce, even with the save of the server and waiting for several minutes.
Please provide a save-file with a train that will reset its schedule in a few seconds.

I highly suspect, that the people were just messing with it.

[Sabbie]

I'm beginning to think so as well. Seems like I jumped to conclusions.

It must have been a coincidence that it happened exactly when I had path problems. Twice..

Can't reproduce it now. Is there a way to log player actions?

I have seen the issue in game, could be a bug



Very many of the trains are in this state

But it still could be one dedicated troll...

I think it must have been one dedicated troll. At some point one guy was driving through trains with a monster train. After I banned him it seemed to stop happening.
