Is it because he already had some building skill when I started the game? I tried to pick one with Building skill, one with some research skill and one with some Devotion skill. The 4th adult had no skills or likes/dislikes and then one kid.
Oh, but I have already gotten one Master Scientist and she started out with her Research in the same spot as my builder's Building tech started. Neither have likes/dislikes that should have any effect. So, what am I doing wrong?
Builders work slower (and have longer distance to travel to get needed things and rascal harasses them more) than scientists so they gain skill slower.
