I can certainly understand that, but when I started out on this mission, it was not clear that it might come to this. I had thought that it was supposed to be an expedition and so put together a good crew. We were forced to leave Bogota before she was able to hire the locals as guides, porters, and other jobs, or the number of people would have been greater. I will remember this for the next time and will limit the number of people involved to as few as possible.
I am sorry for messing up the scenario with multiple NPCs.
