System.InvalidOperationException at ORTS.MSTSWagon.SignalEvent

[disc]

OR have crashed with the written exception, the full message is attached too.

It happened when passing a signal, about 1 hour after the activity start.

I've reloaded a previous savegame (10 min before the crash), and tried again, but the exception didn't happen again.
May be connected to the problem, that the signal should to green from yellow approximately that time when my train passes it. At the crash, it changed just a moment before my train passed it.

The exception has nothing to do with the signal or, indeed, with the player train.
The problem is related to an AI train.
My first guess is that an action 'signal' (like applying or releasing the brakes) is being passed down the train just as this train is removed.
Could you please run from the save again, this time enabling the Dispatcher info display (3x shift-F5), and check if an AI train is removed about the time the crash occured?

Thanks.

There are a lot of AI trains in that activity, but yes there was a train that was removed around that time when the crash happened.

Does the problem still happen with version 1.4?

This problem does not show with 1.4
