Since the saves has been fixed, I got an idea.
Im going to post a save here, anyone who wants to participate can download it and play it. If they want they can do a thread of their own playthrough of the save, so over time each one will have an alternate version of the original timeline. They can do whatever they want on it, will their nichelings evolve to hunters or collectors? Will they go to easier or harder islands? Will they go extinct?
