So I'm playing through coop with my girlfriend but i tend to play ahead more solo and just back track to where she is with a seperate team i keep for that.
I just got my ticket for the airship to the 2nd island and i wanted to make sure i didn't lock myself out of going back to meet up with her.
I see some post talking about certain parts preventing backtracking but i didn't fully grasp what areas or events stop back tracking.
