Here is the Sunda map update for versions 1.57–1.61; I have fixed traffic path issues present in version 1.56 and later versions, and corrected ETS2 default tree models that had definition errors.

Since I own version 1.57, I developed this update using that version. Crashes upon colliding with traffic vehicles may still occur, but you can avoid this by using the specific save profile I have provided for versions 1.58–1.61.

I have tested it on version 1.60; please try it yourself on versions 1.58 and 1.59 using the provided save profile—if no crash occurs upon colliding with traffic, then simply use that save file.

If you create a new profile, the crash issue caused by traffic collisions might recur, as crashes still happened when I tested it using the default Sunda save profile.
