I'm having a similar problem with my TC. I bring him to the pearl and it says he lacks the skills to finish this object. He is 34 years old!!! Yes, he was a child when he became chief about 3-4 days ago. (I have NO IDEA what people are talking about when the talk about time traveling!!! Good thing!!)
But, since he doesn't do any other work, how can I get him the "skills" to complete this job?
