Completely redone the redstone system for the TNT exploding at the end. There were still some redstone torches that could, due to lag, activate the TNT and explode the map. Everything should be fixed now. No more random exploding! Sorry for the inconvenience.
The villager that represents the scientist is now called "Dr. Evil" (above his head), as he is called in the sequel.
Removed the trap doors in the scientist's office that would open when you pull a lever.
