I'll look into any issues or bugs listed here to make sure everything is working as intended.
The hunger not restoring is very possible as I worked on that just before exporting this build.
Materials gathered from plants are their proper names. Gossypium, for example, is the name of the "cotton plant". Linseed is the name of the plant that produces flax, which is spun into fibers that make Linen.
Same goes for the totem sacrifice. I think there might be an issue with how often the objective is checked. Reloading the game checks all objectives on game start, so that might have done it. I'll modify the sacrifice objective check in the next build.
Many of the objectives are not "reasonable" to complete. As some are balanced to late game when a player has 60-100 fully upgraded pawns. The demo does not make it possible to complete many of the objectives.
NPC bathroom need is not yet coded in, I've been doing one need at a time. It will be the next one.
