There are 2 updates:

1. In case you have not seen it yet, the 3D Map is working again
2. I have re-written the plugin that made sure people do not get on top of the nether roof. In the old version, people were pushed back to the spawn area of the nether. This allowed users to cheaply return to the center of the nether when they were far out. Now, the system tries to find a safe place on the same spot starting around height 65 and teleports the player there.
