Hey in my current game, I have a number of my cities still under blockades even though the ships who initiated the blockade are gone. In one case, defeated.... honestly I dont remember which opponent but after I did, my city is still under a blockade and so I cant use any of its water tiles. After my last battle against Greece, I made peace with them but once again my city is still under blockade even though the ship was forced from my border after peace was declared. Any idea what is going on or what I can do to fix it?
