I play with KGCM, XCAI and BAI integrated.
In vanilla and all others mods you take a settlement when you hold the central square for 3 minutes. Why it isn't the case with XAI? It's annoying, because I can keep easily a settlement if I place an unit very far from the centre -usually the ennmy "forget" it, and I can wait till the end, even if all my army is destroyed.
It is a bug, or intended?
