Most people get errors because of early cheating. The game is coded to explore slowly, And choices are making stats rise... if everything is raised to level 5 game will crash or restart to the beginning. Cheat only when you enter the city to level 3 or 4, but only stats like ( strength, agility, technology, shapeshifting etc., and charm only to level 4 because if you have 5 in book 4 (story St.Louis will crash ) and don't cheat lore, finance, status... (wealth you can cheat I mean money, but skill finance never cheat)
The game crashes because of cheating and, with that, eliminates a choice, and when you do not have a choice game crashes or an error appears.
