Happy new year @ravensuominen and @all!
I've finished another "great campaign" with Iroquois, now the CTD problem is solved but there is a new one: Iroquois Conf. country hasn't been correctly converted, it results in a big black blob without any flag, called "user defined". Also Syria and Funj (a single region nation near Egypt) are black countries without flag. All the rest seems well converted.
EDIT
I've converted also a "0-day" save from EU3 and I've noticed that the Iroquois Conf. is the only north-american native country that becomes "user defined": all the other becomes (rightly, I think) Cherokee.
Also Congo and Okinawa (Ryukyu) becomes "user defined", so I've chosen one of three nations (existing in 1399) that aren't well converted, what a misfortune!
Anyway, there is something I can manually edit to become Cherokee as the Iroquois, in the EU3 original save and/or in the converted REV one?
