Hello James, this is fam621. Asking this quick question, does the prices have anything to do with the money that you earn in-game? As I have already went into bankruptcy on one of my pre 13.0 release maps and the default player (Transport Operator) is in over 2 million simutrans money debts. Do you have to do anything to sort out the bankruptcy apart from putting the game on freeplay mode?
Yes and you can try to remediate that by reassigning the classes. I, for instance, have managed to make some lines profitable by reassigning the trains' "Low" class accommodations to "Very low".
Okay, I'm going to do that as of now. :)
