Crash when reading Road/trail/ect Maps

To his defense, yours is a mild case…
Here, this was one of mine that generated with the Aftershock settings without crashing my game:

I see this when travelling over to other the next over map tile or 2 only really seen this once and wasn’t as big. hmm, I’m trying to implement this so people can have it as a mod option maybe it will be made a vanilla “option” in settings but I guess this would need C++ and I’m not there yet for adding this kind of code, when I have time ill self teach my self but I doubt the beginners to advanced will give me everything I need to know, will make a .md for this as well but mainly for my self and will probably only make sense to my self.

I’m lacking the no how to use this function, I have no files on my desktop with this function. so modding with this function is hard without any documentation. i will check into the src folder and look through the hard code (not because it’s hard because it’s compiled into the game) - if people don’t get my meaning.
