changed the difficulty to nightmare

blocking the shortcut wasn't enough and i've tried to fix it again, i give up if someone still manages to find that magic 1,5 minute save! :P

Blocked a shortcut wich allowed people to skip most of the track, but saved it as a seperate track; so now everyone can feel the 1337 of taking the most awkward shortcut in futuristic-racing history..... thanks JnvSor ;)
