I've been playing with the beta patch and I've noticed that once you beat the crap out of the AI, to save on money they remove ALL of their forts. This happened to me after I invaded the Mamluks as the Ottomans (Aleppo, Damascus, even Cairo had no fort), and then Castile did the same, promptly rebuilding a shit ton of them later.
Seems like a huge waste to destroy forts to then spend thousands of ducats building them anew.
