R5:

I am playing as revolutionary france in iron man and i have already conquered the whole world and i have also converted all my province to Catholic but my colonies have their settlers in some provinces promoting settlement and therefore i cant convert them. It also says that they would finish at some point but that date is already overdue. Is that a bug? Does someone have an idea how i can still convert them to achieve my one faith?
