Can't use spawnmenu when deriving from sandbox.

I have tried adding the spawnmenu into TTT by adding


DeriveGamemode("sandbox")

, but it does not work when I press Q or use +menu. I also changed base to sandbox in the terrortown.txt file and it still doesn’t work. Does anybody know how I can get it to work?

Bump

What file are you putting this in?

Shared.lua and terrortown.txt
