Use the duplicator.Problem solved.
It can be done with dup, however, sometimes that is a very bad way to do it, like I am making a space ship, and I cannot clearspambricks because I forgot to put it on a baseplate when I started, and it laggs like hell if I dup it.
I think MasterBlockMan needs some glassses
Duplicator works perfectly fine, just select a baseplate, then delete the original baseplate.
I said clearly that alot of my builds that I want to move lag the entire server when I duplicate it, maybe some people should try out my crappy computer and see where I am coming from :U
