Jesus man, those mappings haven't been touched in over 5 years. They were atrocious. I redid entire anatolia up to persia, and upwards to caucases. Update the converter and retry.
Its a bit better. Thanks.
However, now you don't have Mosul mapping to Mosul and Irbil mapping to Arbil.
Its also may be worth noting that modern Diyarbakır historically replaced Amida. So Amida should probably map to Diyarbakır
Also Ani should probably map to Kars. The Turkish name of Ani is Kars in CK2
After looking through the Turkish and Greek translations in CK2 and EU4, if we take this as a clue for mapping provinces, this is how they should be mapped:
CK2 682 (translated in Turkish to Van) to EU4 2307 (Van)
CK2 672 (translated in Turkish to Erivan) to EU4 419 (translated in Turkish to Erivan)
CK2 681 (translated in Turkish to Kars) to EU4 2204 (Kars)
CK2 703 (translated in Turkish to Erzurum) to EU4 331 (Erzurum)
CK2 683 (Amida) to EU4 418 (translated in Greek to Amida)
CK2 680 (Tao) to EU4 4303 (translated in Georgian to Tao)
Other corrections:
CK2 697 (Mosul) to EU4 411 (Mosul)
CK2 685 (Irbil) to EU4 4293 (Arbil)
