I am playing as Gandhi on a fully crowded standard map (King difficulty). I moved my warrior to find that Alexander's settler was only 4 hexes away from my settler. I moved my settler 1 hex toward Alexander and founded my city. Being only 3 hexes away, Alexander couldn't found his first city on the tile that his settler spawned on. Strangely enough, Alexander didn't move his settler and found a city. He left his settler right where it was, doing nothing, and he didn't even guard his settler with his warrior. The next turn, I had a clear shot at his settler, so I declared war and took it. I then took out his warrior with my warrior. However, he wasn't knocked out of the game. Does he have another unit running around somewhere? Or did he never "lose" his capital and therefore will never be eliminated and always in the game to make diplomatic deals? Has this ever happened to anyone before? I've posted the initial autosave if people are interested. I am playing on a mac.
