Quote from ZeronNTheXeonYou can copy and paste the structures you have built to the new world. This requires little MCEdit knowledge and is better in the long run.
I honestly have no MCEdit knoweledge whatsoever. Could i maybe email you my save and you could try?
(EDIT) I forgot. The save that i am having problems with isnt the one i have all of my creations on, but still has my house. Could you maybe fix it somehow? All i need is my house but not the tinkers construct smeltery
