You
need to keep fighting earthbenders outside the city, maybe. have you visited mai at night? ty lee?Unfortunately when I go to the throne room there's just a Fire Nation guard telling me Azula said I'm not allowed there and going to Zuko's room has had no effect. I haven't been able to get further dialogue with anyone else either. The hooded salesman says he has nothing for me and the alley is empty otherwise. Rei only has her unlocked sex scenes to offer and at night the tower is empty. I've tried to free and imprison the thief and in both cases there's no effect of Azula. Iroh only tells me to wait for Azula to come for me. Mai only offers her shop services after the mission to stop the thief is completed. I actually believe the only thing I haven't tried is freeing one or more of the farm girls.
Thank you for trying to help though.
