[2.0.23] Crash on train under train ghost departing station "this->state == RailConnectionDirection::None was not true"

[txprog]

What did you do?

I ghost build a train in a station that was empty initially.

What happened?

A train came and start to unload at that station.
Constructor bots came and was not able to build the ghosted train because one was at the station.
I manually change the train stopped at the station to go to the next action in its route, to move the train out of the station.
I leaved the popup of the train, watch the train start leaving the station but not fully.
And the game crashed.

What did you expect to happen instead? It might be obvious to you, but do it anyway!

The train should have leave the station, and the bot construct the ghosted train.

Does it happen always, once, or sometimes?

At the moment, only once, but timing is hard to reproduce on this one when you just play casually.

I have a save that reproduce it directly.

On the attached saved:

1. Go to nauvis using map view
2. You should be in front of the train that is stopped, and bots are arriving.
3. When bot are waiting for the ghost train to be constructed, click on the actual locomotive, and put it back on automatic
4. You'll see the train moving out of the station, then the game crash
