Love reading everyone's comments. I had reached and completed all 16 puzzles with success, but kept nurturing my village. Another tumbled-down hut appeared, so I put my Builders to work on it enmass. The hut became completed and is now their clothing hut where they can pay 5000 tech points and pick another suit of clothes. My village has accumulated over 1/2 million tech points! They get to change clothes as much as I like. I still don't have all the tablet pieces in the Collectibles. I also have trouble mating a woman who is in her 50's or older with a guy of any age. Is there a cut-off on the women's breeding age?
