GN Hi-Line Route Crashes at Certain Part of Route

[ThatSolitaryGuy]

I meant to ask about this when I first encountered this problem over a year ago, but ended up sweeping it to the side until I tried reloading this route. I'm also posting this here and NOT in the MSTS discussion session, because I assume that this problem is another compatibility issue between MSTS and OR.

The issue occurred when I loaded the activity, "Hotshot into the Sun" (gnactd06.zip), between Harve and Cutbank. The activity ran well enough, until I made it just west of Xenia, where the program would fail. I examined the player path and any AI paths in the track viewer, and I didn't see any apparent issues with their routing, but I made some minor modifications anyway (mostly adding/removing passing paths). I tried reloading the activity again, only to have the same results. Then, I ran the activity in explorer mode, using a path that starts in Shelby. It ran smoothly again, until it made it to east of Rudyard, where it crashed once again.

I was planning on posting the log files separately, instead of pasting two huge blocks of text, but they're both too big to attach to this post. They mostly list a series of missing shape files and their respective world tile placements, but this problem hasn't caused any crashes in the past. My main focus is on the message that displayed at the end of both of them. Posted below is the message at the end of the western trial. The eastern trial is mostly the same, just a few minor numeric differences.

Error: System.IndexOutOfRangeException: Index was outside the bounds of the array.

Information: Game.PopState()

The best that I could decipher from this is some potential issues with recognizing certain data regarding the world tile/terrain of the route. Hopefully, someone with more experience can clarify why this is happening. If this isn't enough, then I will paste the entire data from both log files if necessary.

Zip the log and attach it to a post here. The error refers to a terrain problem and the full log may contain further information.

Alright, this should cover it.

Again, it's mostly pointing to missing shape file directories, which hasn't caused any crashes for me in the past, unless the amount per tile is overwhelming enough in this case.
