Well I was able to pass 1101 but only a few years later the crashes keep on coming randomly, is there a way I can check crash logs and potentially fix these crashes? And if I were to find a patrician without heir how would I fix the problem.
use "charinfo 1" in the terminal to find out his character id number. then use "play <char id>" to play as him, disband his retinue. switch back using your character id then use "kill <char id>" on him.
you could use the get your wife pregnant cheat on him but if your ctd is consistant within 2 years hes probably 80 or something, and youd have to kill his wife, make him marry someone new and hope he doesnt die in 9 months. and i assume the heir must be male in patrician families.
