I randomly found Outpost Zimonja while exploring and cleared it of enemies. It isn't getting discovered on the map though, meaning its an unmarked location. I set up a recruitment beacon, and used one of the settlers to set up a supply line to Tenpines Bluff. When I check the minimap, there is no supply line to Tenpines Bluff. So basically the game is treating the location like it doesn't exist. After a bit of research, it seems this location is part of a quest given to you by Preston Garvey. Is this the reason why this location is not working? I need to "discover" it through the quest, as opposed to randomly discovering it on my own?
