clone not working? – Redstone Discussion and Mechanisms
Minecraft can load only part of the world at a time. If the Clone command tries to access blocks that are too far away to be loaded, the command doesn’t work and you see the error message “Cannot access blocks outside of the world.”
Why can’t I place blocks outside the world in Minecraft?
Minecraft Forums Anybody know why this happens? This message means that those chunks aren’t loaded into memory, and as such can’t be edited. To make any change in a minecraft world (excluding 3rd party tools) the chunk has to be loaded.May 24, 2016
