System.Collections.Generic.KeyNotFoundException at Orts.Simulation.Signalling.DeadlockInfo.GetEndSection (1.1.3487, AU NSW Craven Timber Railway, Northbound Goods)

[Geoff]

The simulation crashes at the same point in the activity - Craven Timber northbound freight.

This has happened twice, both at the same point in the activity, just as the train is approaching the loop.

A text box with an error report comes up, although the sound continues on. On clicking on OK, you return to the open rails starting screen (where you select the route and activity etc)

The error message in the text box is the same as that shown at the end of the openrailslog.txt file, which I have attached.
