Well, I dont mind that it happened actually because when you get this far in the game, you mostly have to wait for things, where as now, because I neede more builders I can train the whole tribe of 60 and get that statue up quicker Also, I have a thought about why this might happen.

Since I was concentrating on doing other things, the huts never got repaired regularily, I usually do maintenence on them, as once everything is built you have to keep your builders occupied somehow, If one neglects the maintanence of their tribe, maybe things just fall apart Either way is kinda good cause now my villagers have more things to do...3 months worth of work, lol.
