Asking for spawns to be adjusted is the same as asking for a re-arm of the map... as the same tool is used for both...

I took the liberty of re-arming the map and placed some random weapon spawns so that the custom weapons can get in as well as more ammo... It seemed pointless to re-arm for a single spawn fault that sometimes happens...

Feel free to check out the file by placing the script in your garrysmod\maps directory

Note: Gmod Updated to a new location in Steam... so the new gmod directory is C:\Program Files (x86)\Steam\steamapps\common\GarrysMod\garrysmod\maps
