I finished the main story a few days ago and have been going around doing the side quests, the hunting, frontiersmen, homestead missions, etc... and also liberating the forts. Only one fort left to go, according to the walkthroughs I've seen and that's Fort Division in North-East New York. Well, I found the fort, but it's completely occupied by patriots. The red fort icon didn't pop up on my map, not even the white liberated fort icon. What the heck's going on here? Anyone have any ideas?!
