I'm trying to do the final trial since last week and I'm stuck on this part. I've tried to reload, open other save... nothing happened. Gerald get on the boat and lambert is out of the boat. I can show the option to speak to lambet, but he just says "gerald" over and over...... and also I can't sit on the boat. I was doing this mission before, but I was killed. So I tried to up my level and try again. But now this is happening. I'm playing on xbox one.
