I know you are all going to laugh at me for asking this but I have to ask anyway:
How do you sally when under siege?
I was playing a game as Saba and a Ptolemy town rebelled to me and gave me a big army, since it was out of the way, I made type 4 gov with local autonomy so I could leave it alone to focus on my main settlements.
Eventually Ptolemy attacked the town with an army of about 200 men, I could have beaten it easily with almost no loses but for some reason I was unable to sally out and attack them so the outcome was that I lost the town and the good army with it because I was unable to sally.
