I've put a lot of time and effort into the world I have, but I know they changed some things in the last update that would normally require creating a new world to experience. Naturally I'd rather just bring that new stuff over to the world I already have; is that possible? I already know about the graveyard biome (how you're supposed to be able to just create one by setting up graves?) Is there anything else I'll end up missing out on if I remain loyal to my current address?
