If loots doesn't work , here is the fix :

Go into this file : steamapps\common\GarrysMod\garrysmod\data

go into the "murder" subfile (if it doesn't exist then create it)

create a subfile in "murder" named : gm_freddyspizza

then create a txt file named loot.txt

copy paste this in the txt file :
