in the localized form of Iberia, it's listed as "Ibérica", which is incorrect.

"Ibérica" just means "Iberian", as in the "Iberian peninsula/Península Ibérica". The correct name is Iberia.

Suggestion: Rename the Ghurids to Šansabānī(their otl dynastic name). Its derived from Middle Persian Vishnasp via Arabic. Also the Shahis to Uḍi Śāhi, since that was prolly their full dynastic name, and their ruler title to Spalapati.

Thanks for your suggestion!

Iberia should probably not be "Ibérica", since that would just be "The Iberian" (Female), it would be like referring to a kingdom as a subject while also omitting it. It could work if it was "The Iberian Union" (La Unión Iberica/Unión Iberica), but "Las Iberias" (The Iberias) might fit as a parallel to the historical "Las Españas" (The Spains).

Likewise, one who lived there would be an "Ibero" (someone pertaining to Iberia, like "los pueblos iberos") instead of "Ibérico" (pertaining to somewhere, or someone, that is part of Iberia, such as a language or animal, like "el lince ibérico" or "la lengua ibérica").

Thanks brother, I like your mod very much.
Let me add some explanations
The Byzantines called their country Romania (Ρωμανία), their nation Romaioi (ῥωμαίϊκα), and their language Romaic (ῥωμαίϊκα);

Thanks for the correction, I'll put the change on the next update

"Rhomaion" ("Ρωμαίων") on its own simply means "of the Romans".
So this is not what the Byzantines called their country

Ρωμανία

WARNING! Carry on reading! Or you will die, even if you only looked at the word warning! Once there was a little boy called Joey, he was ten-years-old and he lived in a mental hospital because he posted a shitty copypasta onto a People Playground mod's comment section . He got so bad he went to kill all the staff in the hospital so the Feds decided that best idea was to get rid of him so they set up a special room to kill him, as inhumane as possible. And he sat there in agony for hours until he died. Now every week on the day of his death he returns to the person that reads this letter, on a monday night at 12:00 a.m. He creeps into your room and kills you slowly, by pegging you and watching you bleed to death. Now send this to ten other profiles on this one site, and he will haunt someone else who doesn't. This isn't fake. apparently if u copy and paste this to ten comments in the next ten minutes nothing will happen: sorry man i am not taking the risk
