I accidentally joined a modded world without using forge so all of my modded items and blocks got deleted. I found a back up of the world I made 2 days ago and all I did in the last 2 days was create an enderman grinder. I want to merge The End from one save file to the other, is this possible? I'm pretty sure it is, but I don't know how to do it. I think the 'DIM-xx' folders are what I need to swap, but I'm not sure.
