I like most of the sugestion thas was mad in the previous pages.
Some of them the same as mine like rain, Weather causing damage to the huts and research for the healers, mayby some king of pharmacy were they could mix medications for the villagers
(could be an other tech level) I would also like to see more tools being build by the scientist or the builders for different use like farming or hunting.

Could you also possibly build a place to put the totems of make them smaler so we don't get to clutter with them.
