Ever get one that just WON'T work? I have one who was born with a bonus in Building, I trained him under a Master Builder, and now he's "Adept"... but I can NOT get him to build! I literally have to spy on him and every time he runs off, put him back. In about 45 mins I've gotten 3% of my new hut done. grrrr. All he wants to do is dance, dance, dance!
