Also a question i would like answered. I have two main saves one has almost nothing uncovered and was made just before home and hearth and one that has a lot uncovered and was made when the game first went into early access.
I think its recommended but not necessary, but what that really means and if it will cause problems i dont know. I don't think I can sum up the interest to start all over again, even if i use my main character and haul all the decent materials into a new world.
