Fixed spawn issues when playing the weekly challenge.

Fixed Crawler spawn.

Fixed spawn volumes always being seen and not spawning anything.

Got rid of the collision on grass and other vegatation.

Additional fixes

Fixed user submitted exploits (thanks рокегмап!)

Fixed door health having negative health values.

Added actual terrain to the map. (Will be adding hills and other terrain noise soon.)

Added additional staircases to the catwalks. This should make it much more difficult to holdout on the catwalk now.

Gave doors more health so they won't break as easily anymore, makes it much easier to keep doors up and welded. (door health, not weld health)

Reupload to fix server mismatch error.

Added a truck to the eastern field to make it less barren.

Added a few more light sources on the catwalk.

Rotated one of the trader pods for better display.

Added dummies because.

Swapped out streetlamps at the front gate for wall mounted lamps.
