NPC Animations problem.

[Horror]

I have a problem with BigBang's Animation script.

Everymodel I use works, Expect for a set of custom ones made by a friend. (The rest of his custom models work.)

--Hey hey hey! It's fucking NPC animations version three! This time with no Rick Dark shit.
--Credits to Azuisleet ( Original hook ), Entoros( Holdtype thing ), and well, me, Big Bang/F-Nox ( everything else )

local ply = LocalPlayer()

--Override! Thanks Entoros!
function _R.Weapon:GetHoldType()
    if self.HoldType then
        return tostring( self.HoldType )
    end
    return "default" 
end

--Weapons that are always aimed
local AlwaysAimed = 
{
    "weapon_physgun",
    "weapon_physcannon",
    "weapon_frag",
    "weapon_slam",
    "weapon_rpg",
    "gmod_tool"
}

--Weapons that are never aimed
local NeverAimed =
{
    "hands"
}

function MakeUnAim( ply )

    if ValidEntity( ply:GetActiveWeapon() ) then
        if( !ply:GetActiveWeapon():GetDTBool( 1 ) and !table.HasValue( AlwaysAimed, ply:GetActiveWeapon():GetClass()) ) then
            ply:SetNWBool( "aiming", false )
            --ply:GetActiveWeapon():SendWeaponAnim( ACT_VM_HOLSTER )
