I didn't know that the homestead missions in Assassin's Creed were limited to a specific sequence, so I skipped a few thinking I could just do them later on. Unfortunately, I'm now in sequence 7 and I've missed recruiting some people.
Is there a way to go back and pick up those missions? I tried replaying a mission, but the replay ended as soon as the mission did.
I'm on the playstation version, if that makes a difference.
