System.NullReferenceException at Orts.Viewer3D.SceneryMaterial.LoadDayTexture (1.3.1.4328, CPR Mactier Sub, cp_nb_mnfst223)

I have attached the LOF FILE for an activity I ran with the STABLE version of OR as of 11/4/2020. The train operation activity (TOA) ran with the CURRENT STABLE version of OR but then stopped working (crashed) after I placed static consists at industries and in a yard using the TSRE route editor.

I decided to try using the most recent EXPERIMENTAL VERSION of OR as of 11/5/2020 to run the activity. The activity runs without issues with the specified EXPERIMENTAL VERSION of OR. The error I encounter when running the activity with the CURRENT STABLE version of OR: Error: System.NullReferenceException: Object reference not set to an instance of an object. The current STABLE VERSION runs all other TOA's on all my routes. Has anyone reported issues with TOA's after they have revised an activity with the TSRE route editor?

In summary, an activity ran with the stable version of OR, then started crashing. The same activity runs without issues using the current experimental version of OR (as of 11/5/2020).

Thanks for reviewing my issue. Also, thanks to all the developers for creating OR.
