I played a campaign called “Africa – Francisco de Almeida – 5.A Son’s Blood” and successfully achieved the first objective of converting 10 units from the red team.
The second objective was to convert Afonso de Albuquerque, after which my cannon galleons and caravels joined my team.
However, my transport ships still had red team units on them even though they had turned to my team after the truce time expired.
Releasing these units resulted in my ships attacking them.
I eventually killed them all as they were hostile and useless to me.
Additionally, some unit names like Malik Ayyaz and Amir Hussain al-Kurdi were not properly displayed in the game.
Although I am not interested in reporting each instance individually, the developers could consider fixing these issues in future updates.
