Half-life 2+ SNPCs Addon for Gmod Desert Patrol and Arctic patrol combine soldier's don't work

[unreal garden]

i have installed this addon recently into garry's mod called Half-life 2+ SNPCs which adds more combine stuff into the game. recently i spawned the desert patrol combine and the arctic control combine, but when they shoot the flash of the gun comes out but no bullets are shot and i take no damage. i then got a problem at the top of my screen and when i clicked on the problems menu in the pause screen and scrolled down to the Half-life 2 SNPCs section i saw this: [Half-life 2+ SNPCs] lua/weapons/weapon_vj_hl2_ar2/shared.lua:166: bad argument #1 to 'random' (number expected, got nil)

random - [C]:-1

PrimaryAttack - lua/weapons/weapon_vj_hl2_ar2/shared.lua:166

unknown - lua/weapons/weapon_vj_hl2_ar2/shared.lua:317.

i have no idea what this means but hopefully someone can help me fix this issue.

its this addon specifically: https://steamcommunity.com/sharedfiles/filedetails/?id=566678693

leave me a message in the comments of this post once whoever figures the problem out

Anyone there?

most likely an error with the addon itself since it has not been updated in a while
