No way am I restarting. Chances are I will have to start other worlds just to use them to gather resources that won't spawn in my current map. I've spent WAY too many hours building up my viking village that I enjoy spending time in.

I really hope that the Devs can figure out a way to get new items to spawn in already 'mapped' zones. That's probably a lot of work for them though, being it took months to add this 'update'.
