1. Joan of Arc and the arrow injury
She was indeed wounded by a crossbow, but this happened during the first campaign against Paris, and not near Orleans, as is said in her campaign. In the game, there was only one campaign against Paris, although in reality there were two, so the arrow wound was moved to another episode altogether. I understand that making two unsuccessful trips to one location does not make sense in the game, but just one line in the text would be enough to say that there was such a trip and it was there that she was wounded.
But in the campaign of Philip the Good there is a correct mention that there was such an unsuccessful episode.
2. Malik Ayaz the Russian defector?
There were two people with that name. The first one lived in the 11th century and it is about him that there is most information on the Internet. At the beginning, I generally assumed that there was mistake with anachronism. But then it turned out that there was a second one, who was really a contemporary of Frasisco di Almeida. There is little information about him, but from what I was able to find, he was certainly neither Russian (the name has nothing to do with Ru) nor a defector, but most likely a Mamluk. And he outlived Almeida and died of age. Therefore, I would suggest removing his name from Almeida’s final mission and replace him with just some generic ambassador.
3. Vytautas vs Kazikermen
It was in “Vytautas’ Crusade” where we must defeat this city.
But Vytautas died in 1430, and a fortress in Beryslav called Kazi-kermen was built in 1484 by the Crimeans and Ottomans. Tokhtamysh’s residence did exist in Vytautas time, but there was no city and fortress, which were called that.
4. Jan Zizka and the loss of his eye
Zizka is shown as having one eye in his first mission. Although, most likely, he lost his eye in this battle, i.e. in the beginning he should have had both eyes.
At the end of the campaign, he no longer has both eyes, but his model does not change and still shows him as one-eyed.
I listed those not just for fun, I seriously suggest correcting at least some of them.
