I am wondering if there is anyone out there that can help me.

I have completed Puzzle # 1-9 and 11 & 12 and 15 & 16. All Technologies are Fully Researched.

I have 90 Villagers.

In order to solve one of the puzzles I need a Master Scientist and even though I have several Villagers with their skill ticked off as Research however, they will not voluntarily research any longer. They use to at the beginning of the game and they will voluntarily, farm, breed, heal and build but they will no longer research unless I continually drag them to the research table over and over again in order for them to improve on research.

Has anyone else had this problem and is there a solution.

Thanks Very Much
