Cripes, if you can't fix the errors at least fix the messages!
I got a couple dozen AI trains running all over creation and get this at sunset, so I assume an engine or car has a faulty light script - which one? Line 92 would be a great starting point if I had the KUID, otherwise it's useless. Am I supposed to examine every train used in that session to see which one has an error in line 92? OTOH it could even be a building with window lights, there's no way to tell!
That's the worst problem with all of this, the "could I buy a vowel?" nature of error reporting, too much work to figure out what the error means before you can even start to fix it.
