Why not simply move 5k from spawn trough the nether and keep the map?One thing I love about AE, makes it so darn easy for me to package up all my stuff onto some drives, put them in a canvas bag, and when I do a world restart - I can just copy over my player data and unpack all my stuff that I got legitimately. I did that and ever since it's just been terrific if I don't want to start over from scratch.
