First let me say a big HI to everyone. I'm new here but not new to VV. I played the first and have been checking everyday for the second. So I'm underway but I'm having a problem getting 3 master builders. They have built and repaired the huts and removed the thorn patch, what else is there that they can do. They just wonder around being bored. Any idea on what they can do to increase their skill? Thanks so much!!
