However, I have logging turned off as I'm afraid turning it back on might cause problems again. Is there a way to set the logging file in a different folder location? Preferably away from OneDrive folders?

Using Regedit navigate to Computer\HKEY_CURRENT_USER\Software\OpenRails\ORTS
Edit or enter new item named LoggingPath
Type = REG_Z
Data = C:\xxxxxxxxxx\XXXXX (Location of your choice.)

Lately, I've been getting this dreaded notification from O/R. Every time I go to test out one of the routes I recently edited, something like this POPS UP.

Hi Don,
PLEASE attach the OpenRails log file (from your Desktop) the next time you get that message.

However, you say the message occurs when you "go to test out one of the routes I recently edited".
Do you get the message with any route, or just this one?
If it's only the one route, I suggest that you've probably made an error when editing it. Try running the pre-edited route - you DID back it up, didn't you?

Cheers,
Ged

Just about several of my routes been getting that dreadful SYSTEM.NULL REFERENCE message, including my payware routes. Time for me to eliminate the routes is was running that were compatible to Open-Rails and start over from scratch...AGAIN!! UGGGGH!!

If you wish for assistance, attach a log file.

The jpg you posted last time was far too small to be usefull.

A NullReference exception is a general exception when the code expects an object by does not find one. It can have many different causes.

The exception shown in the JPEG references file Traveller.cs at line 867. Here is the code:

                // We're on a junction or end node. Use one of the links to get location and direction information.
                var pin = trackNode.TrPins[0];
                if (pin.Link <= 0 || pin.Link >= TrackNodes.Length)
                    return;
                tn = TrackNodes[pin.Link];       <--- line 867
                tvs = tn.TrVectorNode.TrVectorSections[pin.Direction > 0 ? 0 : tn.TrVectorNode.TrVectorSections.Length - 1];
                ts = TSectionDat.TrackSections.Get(tvs.SectionIndex);
                if (ts == null)
                    return; // This is really bad and we'll have unknown data in the Traveller when the code reads the location and direction!
                to = pin.Direction > 0 ? -trackOffset : GetLength(ts) + trackOffset;

The index into the TrackNodes array is verified in the preceding lines. Thus the expression should reference an existing element in the array. I can't see how this line could produce a NullReference exception.

The following line could produce a NullReference exception if "tn" were null. But that would mean that there is a null element in the TrackNodes array, which in turn may imply an issue with the tracks.

The log file should report if there were problems with track.
