Ima just say that I only steal builds if I really really like them, in which case I credit the original owner. There is one way to screw the saving stuff though. If you use ONLY bricks with modified UI names, I hear that as long as no one else has that UI name modification, then they will not be able to load the bricks and the build will be screwed. Soemone loaded a build with cube prints in my server once and I had forgotten to turn them on so it failed to load said cube prints.
