I'd like to be able to copy sections of a map from one place or another (without worldedit) or to a completely world. On a test server, while it was off, I found that I could move .mca files, essentially overwriting an existing .mca file with an .mca file that I want to replace it with. Started up bukkit, it threw a bunch of errors like: Chunk file at -23,17 is in the wrong location; relocating. (Expected -23, 17, got 9, 17) Wrong location for EntityPig['Pig'/3535, l='test3', x=510.50, y=64.00, z=219.50] in world 'test3'! But it calmed down after awhile, and it looks like it basically worked. I just don't know what the long term problems could be of doing this. Is this not a good solution to my problem? Trying to copy an entire 512x512x256 size area with worldedit just doesn't work. Well, it works, but lags out the server for 1/2 an hour.
