Wagon fence not showing after spines of America

Hey there partner, I’m trying to do the bandit challenge as early as possible and bandit 2 requires me to bring 2 coaches to the wagon fence. The problem I’m having is the wagon fence isn’t showing up after I did the spines of America mission with Hosea. I wanted to know if anyone might know what’s going on as it should be unlocked right after that mission. Thanks for reading
