help please! error when the player turns on the power..?

so i was recently creating a new map (well, more like ive been working on it since kino and been extremely busy with giant packets of study guides for school finals) and i finished the layout and everything, even waypoints. anyways, during the game everything was running fine, i went to go tunr on the power to get the perks, and i was dropped and given this message from the console menu:
any ideas on what i should do..? i would really like to release this map ASAP
(also, i did noclip to get to the power cause i was obviously dropped from the last game)
