I recently downloaded the Tyken Testworld, which is supposed to be a flat, green grass, blue sky area with an underground storage area. I know it works because it worked on my single player world. But when I load it on the multiplayer server, the sky is red, and if you go far enough out, you see a wall, fire, volcanos, and other un-even surfaces. I added the folders to DIM-1 and put the level.dat, level.dat_old, and session.lock in the world folder. What did I do wrong?
DIM-1? I just put the whole folder to the server root directory and rename it properly or set the world name in server.properties to correspond with it.
