Hi. Thanks for all the replies.I have this game on Easy/2X speed.I started my villager on building at the same time as two others, one has been a Master Builder for two days, the other yesterday afternoon. It's 9:15 Eastern time now and my problem builder has been an adept builder for 29 hours. He was 17 when he became an adept builder and he's 32 now. My actual point is, I keep moving him to tasks, he does it, it says Your villager has improved at construction, but on the details screen the blue bar doesn't move, hasn't for ages, and I had no problem up until this particular point on the experience bar, then it just stopped.I guess it's not life and death but it is frustrating!!!
