Hello, I have seen Village Monk's guide for Virtual villagers.

But, unfortunately, I'm not very sure about the 3rd hut.

I have had 25 people already, but, my builders still haven' t build the 3rd house. There was no sign of the uncomplete hut and I have drag my builder to the lower left hand corner next to research table. But nothing happen.

Help please. I thought once I have 25 people which is the magic no. I can build? Why can't I?
