Not sure why this is happening, I quit and reloaded the game a couple of times, and had the same result. I have a situation in a deity game where Rome has requested me to join their war with Montezuma. I agreed and went to war with Rome. I surrounded one of 'Zuma's cities and hit next turn. Quickly I was annihilated by the AI's archer in the little city. It appears for some reason the AI gets to fire his archers twice at me. One bombard from the city and two archer attacks means a unit killed every turn. I get the feeling that there are two archers stacked in this city somehow. This is a big bug right ? I am using a couple of mods, but I checked the mod files and their is no modification on the archer unit. Does this happen in vanilla ? I am using the City State Diplo mod 2.0 v3. Echoes of Ages v10 and Medical Support Units v3. I provided two saves. Test2 is right after I surrounded the city, and right before I hit next turn, and Test3 is the turn (or maybe 2) after that. What is going on here ?
