An addendum to my last bug report. There are two priestesses, two chiefs, and two Vektors in Tikawara when you first get back to Tikawara from the adra island. It is the set of three near the docks that use the old dialogue options. That set of priestess, chief, and Vektor disappears after you talk to the second Vektor at his trading post, where he does trade with you and you have the option to bring him on as ship's cook.
