Quick update to my hut problem. With a max population of 17 villagers, it got stuck at 4% and for 2 days no matter what they did it wouldnt move. 4 of my Villagers died, including the Chief (RIP dear Ranui!) and POOF the percentage started climbing again and we got to 11% So, with my population at 13 ..they can build it, now Im up to 17 again, (thanks to a barrel that washed ashore) and POOF we are stuck at 11%. It seems that if you max out your population at 17 ( I thought the first max was 15, and no, Ive had no twins) they are unable to complete it.

I will update if my % changes when another of my elders passes on!
