So the idea of copy all these structures for the current Era to a new Era based off of the jungle 1.2 biome coding has become, more or less a pain. Reason, terrain needs to be blended from things that were copied over and just one giant mess and loads of work. So, with finding out a few programs and plugins that will allow me to change individual blocks, yes blocks not an entire biome or chunks, I give you guys two options. 1. I randomly choose places in Era and convert them to jungle biomes. Which this, I will need to convert trees in the area to jungle trees or if a desert is converted to make trees and grass. 2. Create a new world, like Eremos, that will be a giant jungle island. Since to my knowledge that pets will not follow you from world to world, there will be a pet shop on the island where you guys can buy ocelot "eggs" to bring with you to your homes in Era to tame them. Edit: This is holding up moving to Era right now. If the majority of the votes is for a new world. It will speed up the process of going back to Era. Then I'll work on the jungle world separately.
