Ive built the sewing hut and pretty love hut....also the briars by the gong and built the cutting tool. Is there another area of vines?

I was hoping that getting my 90000 tech points today would give me another project but then a parrot scared a scientist into a loss of 29000 points so I am worried my two master builders, who are elderly, will die and my chance to get that gong piece is lost. I almost think if so I should start over. :-(

Can I make a health stew for my two elderly master builders?I have 73000 points, 3467 food, and 12 villagers. Will there be a new hut to build after I buy my level three farming? Or can I get that by ncreasing my population?

ps ACK! I am attached to my little villagers....
