bug fix

didn't really need to change the name for what amounts to a bug fix, but decided to anyway.

Observation: Map was fundamentally flawed.
Response: Rebuild the map from the ground up.

I lost a good night's sleep on this.

Note: Pickups don't drop yet for some reason. Looking to fix it.

Renamed so that it won't crash when played by someone who downloaded the original.

This time, the map hould run without invisible walls. I also added fences to the cliffs in spawn (because the first thing people did was walk off) and elongated the skybox because this is supposed to be a skyscraper after all.
